Schindelin 2012: Fiji, with the ImageJ "Blobs" sample image
How to read this page
In this validation, a script plays the scientist. It gives the answers that we wrote before the run, from the methods of the paper. The run is one sample: another run can give different steps and numbers. The model is the AI. The harness is Cuvette, the software around the model: it runs the programs and records each step. A tool call is a request from the model to run one program step. The session record is the log of each message and each step. The claim check is a script that finds each number of the final answer in the step results. The review is a set of fixed rule checks plus a second AI model, the referee, that reads the record. A deviation is a request from the model for a setting that differs from the choice of the scientist. Each Claude model did 3 runs of this paper. This page shows run 3 of each Claude model and the one run of qwen3:8b. The table of values says how many of the Claude runs match.
Opus: 1 of 1 values match, 1 of 1 correct in the final answer. All 3 runs: 1 of 1 values match. Sonnet: 1 of 1 values match, 1 of 1 correct in the final answer. All 3 runs: 1 of 1 values match. Haiku: 1 of 1 values match, 1 of 1 correct in the final answer. All 3 runs: 1 of 1 values match. qwen3:8b: 1 of 1 values match, 1 of 1 correct in the final answer.
The figure in the paper and in the run
As published
The Fiji paper (Schindelin et al. 2012) describes the platform. It has no figure and no table with a particle count for the Blobs image. The known value of 64 particles comes from a run of ImageJ 1.53 with the Default threshold and Analyze Particles, not from the paper.

Schindelin J, Arganda-Carreras I, Frise E, et al.. Fiji: an open-source platform for biological-image analysis. Nature Methods 9(7):676-682 (2012). doi:10.1038/nmeth.2019

What it measured
The paper describes Fiji, a distribution of ImageJ for biological image analysis. It reports no measurement on this image. Blobs is a small sample image that ships with ImageJ. Teachers use it to show how a threshold and a particle count work. We use it to test the choice of object polarity and threshold, and the rule for objects that touch the image edge.
Data
ImageJ sample image Blobs (blobs.gif). Size: 25765 bytes, one 8-bit image of 256 x 254 pixels.
License: No license text was found for this file. It is an NIH ImageJ sample image, and NIH ImageJ is public domain. We use it as a test image only.
The instruction
A script sent this message as the scientist. The file paths point to the fetched data.
The same request in the words of the paper's method:
Here is the blobs sample image from ImageJ. Count the blobs.
Basis: Not from the paper. The request follows the usual ImageJ route for a particle count: an automatic threshold, then Analyze Particles.
Results
Match: a number in the session record is inside the tolerance of the known value. In the final answer: the model also stated the value in its final answer. For a Claude model, each cell shows the run that this page shows. If the three runs differ, the cell also says in how many runs the value matches.

The session
This is the session as the scientist sees it, in order. Decision cards show the answer that the script gave and where that answer comes from. Each step shows the program, its version, the input file hash and the outputs. Click a line to see more.
setup The decision record starts with these values. A script set them before the first message, from the answers that we wrote before the run.
- Image channel to segment: graySource in the tutorial or test suite: The file is a single 8-bit gray image. The paper does not discuss it.
- Bright or dark objects: brightSource in the tutorial or test suite: Not in the paper. The file stores the blobs as high pixel values. An inverted lookup table (LUT) makes them look dark in ImageJ.
- Remove objects that touch the image border: falseSource in the tutorial or test suite: Not in the paper. We count edge objects. The count without them is an optional item.
- Split touching objects with a watershed: falseSource in the tutorial or test suite: Not in the paper. We use no watershed, so touching blobs can count as one.
- Pixel size: 0Source in the tutorial or test suite: The file has no spatial calibration. The paper does not discuss it.
- Unit of replication: images or fieldsSource in the tutorial or test suite: Not in the paper. There is one image, so no statistics across images apply.
harness note A note from the harness to the model. The scientist did not write it.
- Setup values: Design: - What is the unit of replication? (replication_unit): images or fields - Pixel size in micrometers (0 = uncalibrated) (pixel_size): 0 Segmentation: - Image channel to segment (stain_channel): gray - Are the objects bright or dark in that channel? (object_polarity): bright - Remove objects that touch the image border (exclude_border_objects): false - Split touching objects with a watershed (split_touching): false Ask the scientist: Threshold method (threshold_method), Smallest object to count (pixels) (min_object_size). The harness fills these values into your tool calls automatically. If you give a different value, the harness logs a deviation and shows it to the scientist. - Mode is now watch: you run the steps.
Model thinking, summary: I should start by looking at the image and loading the relevant skill first.
Model
I start with the image check and the counting procedure.

}count-objects.Model
The image is a single gray channel, 8-bit, 256 by 254 pixels, with no saturated pixels. The threshold method and the smallest object size are open decisions, so I propose values to the scientist.
propose_change.Result of propose_change: The record already says "otsu" for Threshold method.
propose_change.decision card Change Smallest object to count (pixels)?
The model asks to change "Smallest object to count (pixels)" from 0 to 10. Reason: A small filter of 10 pixels removes noise specks. The blobs are much larger than 10 pixels, so the filter does not remove real blobs. I will check other values for sensitivity.
Options: Change to 10 Keep 0
Suggested: 10 (A small filter of 10 pixels removes noise specks. The blobs are much larger than 10 pixels, so the filter does not remove real blobs. I will check other values for sensitivity.)
Answer 0
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. We use the Analyze Particles default size range of 0 to infinity.
Result of propose_change: The scientist answered. The record now says 0 for Smallest object to count (pixels).
Model
The record now says Otsu and a smallest object size of 0 pixels. Next I count the blobs with these settings.
count_objects (adapter scikit-image).paused The harness paused count_objects until the scientist chose: Threshold method. The decision cards follow.

Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok
decision card Threshold method
The threshold decides which pixels are objects. Different methods can give different counts. The model runs the main methods and shows you the counts before you choose. The model wants to run count_objects.
Options: otsu li triangle isodata yen mean minimum
Suggested: otsu (The model proposed this value when it asked to run the step.)
Data that the model gave for this card
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok n_objects depends on the choice: 64 with otsu, 65 with li, 64 with isodata, 119 with triangle
Answer isodata
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. The ImageJ Default threshold is a variant of IsoData. We use the IsoData method of scikit-image as the nearest match.

}Model thinking, summary: I notice the actual tool used was isodata, not otsu as the record claims—that's a real discrepancy I need to flag. I should run compare_options for threshold_method with otsu included to get the actual comparison count, and also check the foreground fraction polarity.
Model
The tool reports the isodata method, but the record says Otsu. This is a mismatch, so I write a note and run the method comparison.
note Mismatch: the record says threshold method "otsu". The count_objects result says "isodata threshold 124.7", and its manual route shows threshold_method="isodata". I do not report the 64 blobs as an Otsu result until the comparison run confirms the Otsu count.

Compared 5 values of Threshold method as comparison runs of the last step, count_objects (min_object_size=0, stain_channel=gray, object_polarity=bright, exclude_border_objects=false, split_touching=false, pixel_size=0). Only that step was repeated. To compare another step, run it again first. The record still says "isodata". Threshold method n_objects Result otsu 64 ok isodata 64 ok li 65 ok triangle 119 ok yen 67 ok n_objects depends on the choice: 64 with otsu, 64 with isodata, 65 with li, 119 with triangle, 67 with yen

Model thinking, summary: Otsu and isodata both detect 64 objects, while mean and minimum methods produced no result. The table reveals some very small objects and edge-truncated blobs, so I'll check how adjusting the size filter and border setting affects the count.

Model thinking, summary: Since split_touching is false, some high-eccentricity large blobs like label 38 and label 31 look suspicious—they're probably actually two merged blobs rather than single ones, so I should double check against the split_touching comparison.
Model
Some large, long objects (label 38: 902 px², eccentricity 0.92) can be two blobs that touch. I check the watershed split as a comparison.

Compared 2 values of Split touching objects with a watershed as comparison runs of the last step, count_objects (threshold_method=isodata, min_object_size=0, stain_channel=gray, object_polarity=bright, exclude_border_objects=false, pixel_size=0).

Model thinking, summary: The inverted LUT explains the bright blob values, and the 0.34 foreground fraction with ~350 px areas lines up with typical blob sizes. I recall the classic Fiji/ImageJ result for Analyze Particles on the blobs sample with default threshold is 64 particles, which matches here.
Model Answer draft 1. The claim check and the review read it.
I found 64 blobs in blobs.gif with the recorded settings. Otsu and isodata both give 64. The count changes more with the edge and size settings than with the threshold method.
Settings (from count_objects, scikit-image 0.26)
- Image: one gray channel, 8-bit, 256 by 254 pixels, values 8 to 248, no saturated pixels (from inspect_image).
- Channel gray, bright objects, threshold at 124.7.
- Smallest object size: 0 pixels. I proposed 10 pixels, but you set 0.
- Blobs that touch the border are kept. Touching blobs are not split.
- Sizes are in pixels because the pixel size is not set.
Method mismatch. You approved Otsu. The count_objects result and its Python line say isodata, and the later comparison runs say the record holds "isodata". Otsu also gives 64, so the count does not change. I wrote a note about this in the trail.
Main result (count_objects)
- Number of blobs: 64
- Mean area: 347.5 px²
- Median area: 355.5 px²
- Total area: 22243 px²
- Fraction of the image above the threshold: 0.342
Checks: one setting changed at a time (compare_options)
| Setting | Blob count |
|---|---|
| Threshold: otsu / isodata / li / yen / triangle | 64 / 64 / 65 / 67 / 119 |
| Smallest size: 0 / 5 / 10 / 20 / 50 px | 64 / 62 / 62 / 61 / 58 |
| Remove blobs at the border: no / yes | 64 / 46 (18 removed, mean area 384.5 px²) |
| Split touching blobs: no / yes | 64 / 70 (median area 283 px²) |
- Four of the five methods that ran give 64 to 67 blobs. Only triangle gives 119, which is far from the others.
- The "mean" and "minimum" methods were in my request but gave no result, so I have no count for them.
What the blob table shows (blobs_objects.csv)
- Two objects are very small: label 60 is 1 px and label 59 is 3 px. They are probably noise, not blobs.
- A size filter of 5 px removes them and gives 62 blobs.
- The 18 objects at the border are cut-off blobs. Some are small (label 36: 22 px, label 10: 30 px).
- Some large, long objects are probably two blobs that touch, for example label 38 (902 px², eccentricity 0.92). The watershed split adds 6 objects. I did not look at the split outlines.
What is uncertain
- I do not have a hand-drawn mask, so I cannot score the count for accuracy.
- The true count is probably between 62 and 70. That depends on the noise specks and on the touching blobs.
- This is one image, so there is no replicate and no statistics.
Decisions for you
- Do you want Otsu or isodata in the record? Both give 64.
- Do you want a small size filter (5 px) to remove the two specks? That gives 62.
- Do you want to count blobs that touch the border (64), or remove them (46)?
- Do you want to split touching blobs (70)? You must check the outlines before you accept the split.
The outline picture is at count_objects-5/blobs_outlines.png in the session folder. To check the count in Fiji, use Image > Adjust > Threshold, then Analyze > Analyze Particles.
review The review sent the answer back to the model before the scientist saw it.
- The answer uses 65, 67, 119, 20, 50, 67, 119, 22, 38, 0.92 from a comparison run of another option (threshold_method), not from the setting that was chosen. Use the result of the chosen setting, or say clearly that the number is from the comparison. - The answer names otsu, mean for "Threshold method", but the decision record says isodata. Report the value that was used. - 1 number in the answer match no logged tool result: 902. Run the tool that measures each number, or remove the number, or say how you derived it from logged results. - The answer says the scientist approved Otsu and calls isodata a mismatch. The log shows that the scientist chose isodata in answer to q2. The answer then asks the scientist again to choose between Otsu and isodata. The report must state the decision that the scientist made. - The headline says that the count changes more with the edge and size settings than with the threshold method. The logged runs do not support this. Triangle gives 119 against 64, a change of about 86 percent. The border setting changes the count by 18 and the size filter by at most 6. Fix these problems. Then give the answer again.
Model
I correct the report. You chose isodata, and the count used isodata. My earlier note about a mismatch was wrong.
note Correction to the earlier note: the scientist chose isodata. The count_objects run used isodata as recorded. There is no mismatch.
Model The model writes its answer. The claim check reads it. See the final answer.
The final answer
The model wrote this answer. The harness shows it to the scientist after the review.
I found 64 blobs in blobs.gif with your chosen settings. The threshold method can change the count the most. The triangle method gives 119 blobs, but the other methods give 64 to 67.
Settings you chose (count_objects, scikit-image 0.26)
- Image: one gray channel, 8-bit, 256 by 254 pixels, values 8 to 248, no saturated pixels (from inspect_image).
- Gray channel, bright objects, isodata threshold at 124.7.
- Smallest object size: 0 pixels.
- Blobs that touch the border are kept. Touching blobs are not split.
- Sizes are in pixels because the pixel size is not set.
Main result (count_objects with your settings)
- Number of blobs: 64
- Mean area: 347.5 px²
- Median area: 355.5 px²
- Total area: 22243 px²
- Fraction of the image above the threshold: 0.342
Comparison runs (compare_options)
These numbers are checks only. They are not the result. Each run changes one setting and keeps your other settings.
| Setting that changed | Blob count |
|---|---|
| Threshold: isodata (chosen) / otsu / li / yen / triangle | 64 / 64 / 65 / 67 / 119 |
| Smallest size: 0 (chosen) / 5 / 10 / 20 / 50 px | 64 / 62 / 62 / 61 / 58 |
| Remove blobs at the border: no (chosen) / yes | 64 / 46 (18 removed) |
| Split touching blobs: no (chosen) / yes | 64 / 70 |
- Triangle changes the count the most. The other methods give 64 to 67 blobs.
- Removing border blobs takes away 18 blobs. The size filters take away at most 6.
- I also asked for the "mean" and "minimum" methods, but they gave no result. I have no count for them.
What the blob table shows (I read blobs_objects.csv, the per-blob table of your chosen run)
- Two objects are very small: label 60 is 1 px² and label 59 is 3 px². They are probably noise, not blobs.
- Some objects at the image edge are cut-off blobs, for example label 36 (22 px²) and label 10 (30 px²).
- Some large, long objects are probably two blobs that touch. One example is label 38: 902 px², eccentricity 0.9179.
- These are my readings of the table. I did not look at the outline picture to confirm them.
What is uncertain
- I do not have a hand-drawn mask, so I cannot score the count for accuracy.
- With the methods other than triangle, the comparison runs give about 58 to 70 blobs. Where the true count falls in that range depends on the specks, the edge blobs and the touching blobs.
- This is one image, so there is no replicate and no statistics.
Optional changes you can make
- A size filter of 5 px removes the two specks. The comparison run gives 62 blobs.
- Removing border blobs gives 46 blobs (comparison run).
- A watershed split of touching blobs gives 70 (comparison run). You must check the outlines before you accept this.
The outline picture is at count_objects-5/blobs_outlines.png in the session folder. To check the count in Fiji, use Image > Adjust > Threshold, then Analyze > Analyze Particles.
Settings and step results that the answer does not mention. The harness adds them.
Settings used, from the decision record: Pixel size in micrometers (0 = uncalibrated): 0 · Image channel to segment: gray · Are the objects bright or dark in that channel?: bright · Threshold method: isodata · Smallest object to count (pixels): 0 · Remove objects that touch the image border: false · Split touching objects with a watershed: false.
Values that are not scored
- A trap value is the result of a wrong method, for example an unpaired test on paired data. A trap value in a main step means that the run used the wrong method. A trap value in a comparison run is correct, because the record keeps the scientist's choice.
- An optional value is a second result of the same method. The run can compute it or not.
- A reference value comes from a different program version or a check run by us. We show it for comparison.

Checks
Review findings
The review recorded 12 findings. A rule finding comes from a fixed check in the harness. A referee finding comes from a second model that reads the record. The harness shows the findings to the scientist with the final answer. The record does not mark a finding as fixed. Thus a finding from an early review round can apply to a draft that the model corrected later.
| Severity | From | Finding | Shown with the final answer |
|---|---|---|---|
| error | rulenumber_from_comparison | The answer uses 119, 67, 65, 67, 119, 20, 50, 67, 22, 38 from a comparison run of another option (threshold_method), not from the setting that was chosen. Use the result of the chosen setting, or say clearly that the number is from the comparison. | yes |
| error | ruledecision_misreported | The answer names triangle, mean for "Threshold method", but the decision record says isodata. Report the value that was used. | yes |
| error | ruleunsourced_numbers | 1 number in the answer match no logged tool result: 902. Run the tool that measures each number, or remove the number, or say how you derived it from logged results. | yes |
| warning | ruleborder_objects_kept | Objects that touch the border are in the count. Report the count with and without them. | yes |
| warning | ruleno_size_filter | No size filter was used. Tiny pixel groups count as objects. Show the count at other sizes. | yes |
| info | ruletext_style | The answer breaks the text rules (ASD-STE100) in 4 places. Sentence 8 uses the passive voice: "are kept". Use the active voice. Sentence 9 uses the passive voice: "are not split". Use the active voice. Sentence 10 uses the passive voice: "is not set". Use the active voice. Sentence 30 uses the passive voice: "are cut". Use the active voice. | yes |
| warning | referee model | The answer gives label 38 as 902 px² with eccentricity 0.9179. No logged result shows the value 902. The CSV read at step 8 returned only a byte count, so the log cannot confirm this example. | yes |
| warning | referee model | The answer says the non-triangle runs give about 58 to 70 blobs and that the true count depends on specks, edge blobs and touching blobs. But the border-removal run gives 46, which is outside that range. The range must include 46 or must say that it leaves out the border setting. | yes |
| info | referee model | compare_options asked for 7 threshold methods but compared only 5. The answer says that mean and minimum gave no result. It does not give a reason, and the log does not show why these runs failed. | yes |
| info | referee model | The record for the threshold method is inconsistent. Step 3 said that the record already holds otsu, but the later decision shows null changed to isodata. The agent saved a false mismatch note and then corrected it. The final answer uses isodata, as the scientist chose. | yes |
| info | referee model | Triangle gives 119 blobs against 64 for isodata, a change of more than 20 percent. The answer states this. The triangle median area is 21 px, which suggests fragments. The answer does not use this value to explain why triangle differs. | yes |
| info | referee model | The answer suggests a watershed split (70 blobs) and says that touching blobs are likely present. But the agent did not look at the outline image. These readings are not confirmed, and the answer correctly says so. | yes |
Numbers in the answer
The last claim check read 59 numbers in the answer. 56 numbers match a logged result. 1 number have no source in the record.
Numbers that do not match a logged result (3)
- calculated from numbers in the record: They are probably noise, not blobs.
- calculated from numbers in the record: - Some large, long objects are probably two blobs that touch.
- no source in the record: One example is label 38: 902 px², eccentricity 0.9179.

Data integrity
Each data file has the same SHA-256 hash now as at the time of the step that read it. Where the download script (fetch.sh) gives a hash, the file also has that hash. The run did not change the data.
| File | SHA-256 | Fetched data | Steps with this hash |

A SHA-256 hash is a fingerprint of the file contents. If one byte of the file changes, the hash changes. The table shows the first 12 characters.

- Image channel to segment: graySource in the tutorial or test suite: The file is a single 8-bit gray image. The paper does not discuss it.
- Bright or dark objects: brightSource in the tutorial or test suite: Not in the paper. The file stores the blobs as high pixel values. An inverted lookup table (LUT) makes them look dark in ImageJ.
- Remove objects that touch the image border: falseSource in the tutorial or test suite: Not in the paper. We count edge objects. The count without them is an optional item.
- Split touching objects with a watershed: falseSource in the tutorial or test suite: Not in the paper. We use no watershed, so touching blobs can count as one.
- Pixel size: 0Source in the tutorial or test suite: The file has no spatial calibration. The paper does not discuss it.
- Unit of replication: images or fieldsSource in the tutorial or test suite: Not in the paper. There is one image, so no statistics across images apply.

}comparison Comparison runs for Threshold method. The record keeps the scientist's choice.
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok
decision card Threshold method
The threshold decides which pixels are objects. Different methods can give different counts. The model runs the main methods and shows you the counts before you choose. The model wants to run count_objects.
Options: otsu li triangle isodata yen mean minimum
Suggested: otsu (This is the adapter default.)
Data that the model gave for this card
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok n_objects depends on the choice: 64 with otsu, 65 with li, 64 with isodata, 119 with triangle
Answer isodata
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. The ImageJ Default threshold is a variant of IsoData. We use the IsoData method of scikit-image as the nearest match.

decision card Smallest object to count (pixels)
Pixel groups with fewer pixels are removed before counting. Use 0 to keep all of them. Tiny groups are often noise and can change the count by a large factor. The model wants to run count_objects.
Suggested: 0 (This is the adapter default.)

Smallest object to count (pixels) n_objects Result 0 64 ok 15 61 ok 30 60 ok 60 57 ok n_objects depends on the choice: 64 with 0, 61 with 15, 60 with 30, 57 with 60
Answer 0
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. We use the Analyze Particles default size range of 0 to infinity.

Model thinking, summary: The minimum size question remains unresolved, so I'll just keep it at 0 for now and flag it in the report. I suspect that finding 119 triangles suggests over-segmentation, but I haven't verified this, so I should note it as uncertain rather than stating it as fact.
Model The model writes its answer. The claim check reads it. See the final answer.
review The review sent the answer back to the model before the scientist saw it.
- The answer uses 65, 119, 15, 65, 119, 15, 15 from a comparison run of another option (threshold_method), not from the setting that was chosen. Use the result of the chosen setting, or say clearly that the number is from the comparison. - The answer names triangle for "Threshold method", but the decision record says isodata. Report the value that was used. Fix these problems. Then give the answer again.
Model Answer draft 2. The claim check and the review read it.
Main result: I counted 64 blobs in blobs.gif with isodata thresholding (step 1, count_objects). This is the only result. Every other number below comes from comparison runs that I did not choose as the result.
Settings used (decision record)
- Library: scikit-image 0.26.
- Image: 256 by 254 pixels, 8-bit, gray channel. There are no saturated pixels and it is not a JPEG file.
- Objects: bright.
- Threshold method: isodata, cutoff 124.7 on the 0 to 255 scale.
- Smallest object: 0 pixels. Nothing was removed.
- Border objects: kept. Watershed splitting: off.
- Pixel size: 0, so sizes are in pixels.
What I measured (step 1, isodata)
- Count: 64 objects.
- Mean area: 347.5 px². Median area: 355.5 px².
- Total area: 22243 px², which is 34.2% of the image.
- Per-object table: blobs_objects.csv. Label image: blobs_labels.tif. Outline image: blobs_outlines.png.
Comparison runs (the record still says isodata and 0 pixels)
- These runs only show how far the count can move. They are not results.
- Threshold method, with a minimum size of 0 pixels:
- otsu: 64 objects.
- li: 65 objects.
- triangle: 119 objects.
- Smallest object, with isodata:
- 15 pixels: 61 objects.
- 30 pixels: 60 objects.
- 60 pixels: 57 objects.
What I infer
- Otsu and li stay within one object of the isodata count. The count of 64 holds for these three methods.
- Triangle gives a much higher count. I did not look at its outlines, so I do not know why.
- Size filters of 15 to 60 pixels would remove some small objects. I did not check which ones they are.
What is uncertain
- I did not check the outline PNG for touching blobs that count as one object. Watershed is off, so the count can be too low.
- This is one image, so n = 1. I computed no statistics.
- I have no hand-drawn mask, so I did not score the segmentation.
What waits for the scientist
- The smallest object size is not decided. I used 0 pixels. Choose a value if you want to remove small specks.
- Decide whether to turn on watershed splitting and check the outlines.
The final answer
The model wrote this answer. The harness shows it to the scientist after the review.
I counted 64 blobs in blobs.gif with isodata thresholding (step 1, count_objects). I used a minimum size of 0 pixels, so the count includes small specks. That setting is still open, and the count depends on it.
Settings
- Library: scikit-image 0.26.
- Image: 256 by 254 pixels, 8-bit, gray channel. There are no saturated pixels and it is not a JPEG file.
- Objects: bright.
- Threshold: isodata, cutoff 124.7 on the 0 to 255 scale.
- Smallest object: 0 pixels. Nothing was removed.
- Border objects: kept. Watershed splitting: off.
- Pixel size: 0, so sizes are in pixels.
What I measured
- Count: 64 objects (step 1).
- Mean area: 347.5 px². Median area: 355.5 px².
- Total area: 22243 px², which is 34.2% of the image.
- Per-object table: blobs_objects.csv, with area, centroid, perimeter and eccentricity.
- Label image: blobs_labels.tif.
- Outline image: blobs_outlines.png.
Sensitivity checks (comparison runs, not results)
| Threshold method | Count |
|---|---|
| otsu | 64 |
| li | 65 |
| isodata | 64 |
| triangle | 119 |
| Smallest object (pixels) | Count |
|---|---|
| 0 | 64 |
| 15 | 61 |
| 30 | 60 |
| 60 | 57 |
What I infer
- Otsu, li and isodata agree within one object (64 to 65).
- Triangle gives 119. I did not look at its outlines. A lower cutoff probably splits or adds objects, but that is a guess.
- A size filter of 15 to 60 pixels removes 3 to 7 small objects. The mean area is 347.5 px², so these are small specks or cut-off blobs at the image edge. I did not check which.
- The count of 64 holds for otsu, li and isodata. It depends on the method if triangle is an option.
What is uncertain
- I did not check the outline PNG for touching blobs that count as one object. Watershed is off, so the count can be too low.
- This is one image, so n = 1. I computed no statistics.
- I have no hand-drawn mask, so I did not score the segmentation.
What waits for the scientist
- The smallest object size is not decided. I used 0 pixels. Choose a value, for example 15 to 30 pixels, if you want to remove specks.
- Decide whether to turn on watershed splitting and check the outlines.
Settings and step results that the answer does not mention. The harness adds them.
Settings used, from the decision record: Pixel size in micrometers (0 = uncalibrated): 0 · Image channel to segment: gray · Are the objects bright or dark in that channel?: bright · Threshold method: isodata · Smallest object to count (pixels): 0 · Remove objects that touch the image border: false · Split touching objects with a watershed: false.
Values that are not scored
- A trap value is the result of a wrong method, for example an unpaired test on paired data. A trap value in a main step means that the run used the wrong method. A trap value in a comparison run is correct, because the record keeps the scientist's choice.
- An optional value is a second result of the same method. The run can compute it or not.
- A reference value comes from a different program version or a check run by us. We show it for comparison.

Checks
Review findings
The review recorded 12 findings. A rule finding comes from a fixed check in the harness. A referee finding comes from a second model that reads the record. The harness shows the findings to the scientist with the final answer. The record does not mark a finding as fixed. Thus a finding from an early review round can apply to a draft that the model corrected later.
| Severity | From | Finding | Shown with the final answer |
|---|---|---|---|
| error | rulenumber_from_comparison | The answer uses 65, 119, 15, 65, 119, 15, 15 from a comparison run of another option (threshold_method), not from the setting that was chosen. Use the result of the chosen setting, or say clearly that the number is from the comparison. | yes |
| error | ruledecision_misreported | The answer names triangle for "Threshold method", but the decision record says isodata. Report the value that was used. | yes |
| warning | ruleborder_objects_kept | Objects that touch the border are in the count. Report the count with and without them. | yes |
| warning | ruleno_size_filter | No size filter was used. Tiny pixel groups count as objects. Show the count at other sizes. | yes |
| info | ruletext_style | The answer breaks the text rules (ASD-STE100) in 2 places. Sentence 11 uses the passive voice: "was removed". Use the active voice. Sentence 41 uses the passive voice: "is not decided". Use the active voice. | yes |
| warning | referee model | The size-filter values 15, 30 and 60 do not appear in any logged result. The comparison runs show only the counts (61, 60, 57) and the removed numbers (3, 4, 7), not the settings that produced them. The table pairing is therefore unverified. | yes |
| warning | referee model | The report says the minimum size of 0 is 'still open'. The scientist answered 0 at q2, so this is a recorded decision. The report misstates it. | yes |
| warning | referee model | Triangle gives 119 objects against 64 for the other methods. That is far more than a 20 percent change. The log shows foreground fraction 0.64 and median area 21 px. This points to background or noise being counted as objects. The report calls this a guess about splitting and does not mention the foreground fraction or the median. | yes |
| warning | referee model | The claim that the 3 to 7 removed objects are 'small specks or cut-off blobs at the image edge' has no support. The log shows removed_border 0, and the report says it did not check which objects were removed. The reasoning 'the mean area is 347.5, so these are specks' does not follow. | yes |
| info | referee model | The report says the count of 64 'holds' for otsu, li and isodata. Otsu and isodata give identical areas. Li gives 65 objects with a total area about 12 percent larger. The count is stable, but the object sizes are not. | yes |
| info | referee model | The report names scikit-image 0.26 and labels the count as 'step 1'. No logged result shows the library version. The count was made in step 3. | yes |
| info | referee model | The report states n = 1 and gives no p-value. It does not claim hand-drawn mask scoring. It handles the replication unit and the units (pixels) correctly. | yes |
Numbers in the answer
The last claim check read 40 numbers in the answer. 39 numbers match a logged result. 0 numbers have no source in the record.
Numbers that do not match a logged result (1)
- calculated from numbers in the record: A lower cutoff probably splits or adds objects, but that is a guess.
Deviations
The model did not try to change a choice of the scientist.
Failed tool calls
No tool call failed.
Data integrity
Each data file has the same SHA-256 hash now as at the time of the step that read it. Where the download script (fetch.sh) gives a hash, the file also has that hash. The run did not change the data.
| File | SHA-256 | Fetched data | Steps with this hash |
|---|---|---|---|

A SHA-256 hash is a fingerprint of the file contents. If one byte of the file changes, the hash changes. The table shows the first 12 characters.
How to repeat it
Get the data. The script downloads the files and checks their SHA-256 hashes where it lists them.

The session
This is the session as the scientist sees it, in order. Decision cards show the answer that the script gave and where that answer comes from. Each step shows the program, its version, the input file hash and the outputs. Click a line to see more.
setup The decision record starts with these values. A script set them before the first message, from the answers that we wrote before the run.
- Image channel to segment: graySource in the tutorial or test suite: The file is a single 8-bit gray image. The paper does not discuss it.
- Bright or dark objects: brightSource in the tutorial or test suite: Not in the paper. The file stores the blobs as high pixel values. An inverted lookup table (LUT) makes them look dark in ImageJ.
- Remove objects that touch the image border: falseSource in the tutorial or test suite: Not in the paper. We count edge objects. The count without them is an optional item.
- Split touching objects with a watershed: falseSource in the tutorial or test suite: Not in the paper. We use no watershed, so touching blobs can count as one.
- Pixel size: 0Source in the tutorial or test suite: The file has no spatial calibration. The paper does not discuss it.
- Unit of replication: images or fieldsSource in the tutorial or test suite: Not in the paper. There is one image, so no statistics across images apply.
harness note A note from the harness to the model. The scientist did not write it.
- Setup values: Design: - What is the unit of replication? (replication_unit): images or fields - Pixel size in micrometers (0 = uncalibrated) (pixel_size): 0 Segmentation: - Image channel to segment (stain_channel): gray - Are the objects bright or dark in that channel? (object_polarity): bright - Remove objects that touch the image border (exclude_border_objects): false - Split touching objects with a watershed (split_touching): false Ask the scientist: Threshold method (threshold_method), Smallest object to count (pixels) (min_object_size). The harness fills these values into your tool calls automatically. If you give a different value, the harness logs a deviation and shows it to the scientist. - Mode is now watch: you run the steps.
Model thinking, summary: I should start by inspecting the image as the standard process requires. Threshold method and minimum object size are decisions that belong to the scientist, so I'll need to ask about those rather than assume values myself.
Model
I will inspect the image first to check its channels, bit depth and any warnings.

}comparison Comparison runs for Threshold method. The record keeps the scientist's choice.
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok
decision card Threshold method
The threshold decides which pixels are objects. Different methods can give different counts. The model runs the main methods and shows you the counts before you choose. The model wants to run count_objects.
Options: otsu li triangle isodata yen mean minimum
Suggested: otsu (The model proposed this value when it asked to run the step.)
Data that the model gave for this card
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok n_objects depends on the choice: 64 with otsu, 65 with li, 64 with isodata, 119 with triangle
Answer isodata
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. The ImageJ Default threshold is a variant of IsoData. We use the IsoData method of scikit-image as the nearest match.

What is the smallest object to count, in pixels? The run so far used 0, which keeps every object.
Options: 0 (keep every object) A value you give, in pixels
Suggested: Keep 0 for this image, then check the small objects in the outline picture. (The size filter changes the count. No answer for this decision is on file yet.)
Answer Keep 0 for this image, then check the small objects in the outline picture.
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper.
Result of ask_scientist: The scientist answered: Keep 0 for this image, then check the small objects in the outline picture. (a script gave the answer that we wrote before the run)
Model
The isodata run gave 64 objects. The compare output does not include a result for minimum, so I will treat that method as not reported. Next, I will check the object sizes in the isodata table for very small objects.
The model runs run_script.

p = "count_objects-9/blobs_objects.csv"
df = pd.read_csv(p)
a = df["area_px"].sort_values()

print("count under 50 px", int((a < 50).sum()))
print("count under 100 px", int((a < 100).sum()))run_script. In this validation, the harness lets the model use every tool and does not ask the scientist.step n16 run_script
The script ran in {work} and wrote 0 new file(s) to {work}.

Model
Result: the image has 64 blobs (isodata threshold, no size filter).
What I did
- Inspected the file. It is one 8-bit gray channel, 256 by 254 pixels, with no saturated pixels.
- Ran count_objects with isodata thresholding, bright objects, gray channel, minimum object size 0, no border removal and no watershed split. The threshold was 124.7. This run gave 64 objects.
- Ran the other threshold methods as comparison runs. The record still uses isodata.
- Checked the object sizes in the isodata result.
Settings to report
- Channel: gray (the only channel)
- Threshold method: isodata (scientist choice). Threshold value 124.7.
- Polarity: bright
- Smallest object size: 0 pixels (scientist answer: keep 0 and check the small objects)
- Border objects: kept (not removed)
- Watershed split: off
- Library: scikit-image 0.26
- Pixel size: uncalibrated, so sizes are in pixels
Found
- Isodata: 64 objects. Median area is 355.5 pixels. Total area is 22,243 pixels.
- Threshold range from the comparison runs: otsu 64, yen 67, li 65, mean 65, triangle 119. The minimum method gave no result in the comparison, so it is not in the range.
- Triangle gives a much higher count (119). It picks a lower threshold that separates the blobs into more pieces or picks up background. Treat triangle as an outlier, not as a second valid count.
- Without triangle, the count is 64 to 67 across the methods I could check. Isodata is at the low end of that range.
- Small objects: the isodata result has 6 objects under 50 pixels. The two smallest have areas of 1 and 3 pixels. These are likely specks, not blobs. A size filter would remove them.
- The two largest objects (858 and 902 pixels) are about twice the median area. They may be two touching blobs. I did not check them.
Uncertain
- The count depends on the smallest object size. The 1 and 3 pixel specks are counted at size 0.
- The two large objects may be merged blobs. A watershed split would test this. The current setting is off.
- There is no hand-drawn truth mask for this image, so I did not compute Dice or F1.
- The count comes from one image. It is one replicate. I did not compute any p-value.
Waiting for the scientist
- Decide whether to remove the specks under a set size, and what size to use. The current value is 0. Check the outline picture first.
- Decide whether to test a watershed split for the two large objects.

harness note A note from the harness to the model. The scientist did not write it.
- Your plan still has steps that are not done: Count bright objects with the default threshold method (Otsu) and a size filter; Compare the threshold methods to get a count range; Report the channel, polarity, threshold, size filter, border and watershed settings, and the scikit-image version 0.26. Do the next one now with a tool. If a step cannot be done, call plan and mark it skipped with the reason. Then give the answer, with every number the request asks for.
plan The model updates its plan.
- done Inspect the image (one 8-bit gray channel, no saturation)
- done Count bright objects with isodata (scientist choice), smallest object size 0: 64 objects
- done Compare the threshold methods: otsu 64, li 65, triangle 119, yen 67, mean 65; minimum gave no result
- done Report the channel, polarity, threshold, size filter, border and watershed settings, and scikit-image 0.26
- skipped Size filter: skipped as a separate run. The scientist answered 0 (keep all). The 1 and 3 pixel specks stay in the count until the scientist decides.
Model Answer draft 1. The claim check and the review read it.
Result: the image has 64 blobs. The count uses isodata thresholding, bright objects, and no size filter.
Steps
- Inspected the file. It is one 8-bit gray channel, 256 by 254 pixels, with no saturated pixels.
- Ran count_objects with isodata (the scientist choice), bright objects, gray channel, smallest object size 0, border objects kept, and no watershed split. The threshold is 124.7. This gave 64 objects.
- Ran the other threshold methods as comparison runs. The record still says isodata.
- Checked the object sizes in the isodata table.
- Updated the plan. The separate Otsu run with a size filter is skipped. The scientist set the size to 0, and the run used isodata, not Otsu.
Settings
- Channel: gray (the only channel)
- Threshold method: isodata. Threshold value 124.7.
- Polarity: bright
- Smallest object size: 0 pixels
- Border objects: kept
- Watershed split: off
- Library: scikit-image 0.26
- Pixel size: uncalibrated, so sizes are in pixels
Found
- Isodata: 64 objects. Median area is 355.5 pixels. Total area is 22,243 pixels.
- Other methods (step 3): otsu 64, li 65, mean 65, yen 67, triangle 119. The minimum method gave no result, so it is not in the range.
- Triangle is an outlier. It gives a much higher count, probably from splitting blobs or picking up background.
- Without triangle, the count is 64 to 67 across the methods checked.
- Six objects are under 50 pixels. The two smallest are 1 and 3 pixels. These are likely specks.
- The two largest objects (858 and 902 pixels) are about twice the median area. They may be two touching blobs. I did not check them.
Uncertain
- The count changes if the specks are removed. The size is 0 for now.
- The two large objects may be merged. A watershed split would test this, but it is off.
- There is no hand-drawn truth mask, so I did not compute Dice or F1.
- The count is from one image. That image is one replicate. I computed no p-value.
Waiting for the scientist
- Decide whether to remove the tiny specks, and at what size.
- Decide whether to test a watershed split for the two large objects.

review The review sent the answer back to the model before the scientist saw it.
- The answer uses 65, 65, 67, 119, 67 from a comparison run of another option (threshold_method), not from the setting that was chosen. Use the result of the chosen setting, or say clearly that the number is from the comparison. - The answer names minimum for "Threshold method", but the decision record says isodata. Report the value that was used. - 2 numbers in the answer match no logged tool result: 858, 902. Run the tool that measures each number, or remove the number, or say how you derived it from logged results. Fix these problems. Then give the answer again.
Model The model writes its answer. The claim check reads it. See the final answer.
The final answer
The model wrote this answer. The harness shows it to the scientist after the review.
Result: the image has 64 blobs. This count uses the chosen threshold method, isodata, with bright objects, a smallest object size of 0 pixels, border objects kept, and no watershed split.
Steps
- Inspected the file. It is one 8-bit gray channel, 256 by 254 pixels, with no saturated pixels.
- Ran count_objects with the chosen threshold method, isodata. The threshold is 124.7. The run gave 64 objects. (count_objects summary)
- Ran the other threshold methods as comparison runs (compare_options). The record still says isodata. These counts are comparison results only. They are not the chosen setting.
- Checked the object sizes in the isodata object table (run_script output).
Settings used
- Channel: gray (the only channel)
- Threshold method: isodata (chosen setting). Threshold value 124.7.
- Polarity: bright
- Smallest object size: 0 pixels
- Border objects: kept
- Watershed split: off
- Library: scikit-image 0.26
- Pixel size: uncalibrated, so sizes are in pixels
Found
- Chosen setting, isodata: 64 objects. Median area is 355.5 pixels. Total area is 22,243 pixels. (count_objects metrics)
- Comparison runs only (compare_options), other threshold methods: otsu 64, li 65, mean 65, yen 67, triangle 119.
- Triangle gives a much higher count than the other methods. I did not check why.
- The isodata result has 6 objects under 50 pixels. The two smallest are 1 and 3 pixels. These can be specks. (run_script output)
- The five largest objects have areas of 658, 660, 676, 858 and 902 pixels. (run_script output) These can be two touching blobs. I did not check them.
Uncertain
- The count changes if the small specks are removed. The current size is 0.
- The large objects can be merged blobs. A watershed split would test this. The split is off.
- There is no hand-drawn truth mask, so I did not compute Dice or F1 score.
- The count is from one image. That image is one replicate. I computed no p-value.
Waiting for the scientist
- Decide whether to remove the tiny specks, and at what size.

Settings and step results that the answer does not mention. The harness adds them.
Step results that the answer does not mention, from the record:
- n16 run_script: The script ran in {work} and wrote 0 new file(s) to {work}.
Settings used, from the decision record: Pixel size in micrometers (0 = uncalibrated): 0 · Image channel to segment: gray · Are the objects bright or dark in that channel?: bright · Threshold method: isodata · Smallest object to count (pixels): 0 · Remove objects that touch the image border: false · Split touching objects with a watershed: false.Values that are not scored
- A trap value is the result of a wrong method, for example an unpaired test on paired data. A trap value in a main step means that the run used the wrong method. A trap value in a comparison run is correct, because the record keeps the scientist's choice.
- An optional value is a second result of the same method. The run can compute it or not.
- A reference value comes from a different program version or a check run by us. We show it for comparison.

Checks
Review findings
The review recorded 10 findings. A rule finding comes from a fixed check in the harness. A referee finding comes from a second model that reads the record. The harness shows the findings to the scientist with the final answer. The record does not mark a finding as fixed. Thus a finding from an early review round can apply to a draft that the model corrected later.
| Severity | From | Finding | Shown with the final answer |
|---|---|---|---|
| error | ruleunsourced_numbers | 3 numbers in the answer match no logged tool result: 676, 858, 902. Run the tool that measures each number, or remove the number, or say how you derived it from logged results. | yes |
| warning | ruleborder_objects_kept | Objects that touch the border are in the count. Report the count with and without them. | yes |
| warning | ruleno_size_filter | No size filter was used. Tiny pixel groups count as objects. Show the count at other sizes. | yes |
| info | ruletext_style | The answer breaks the text rules (ASD-STE100) in 2 places. Sentence 37 uses the passive voice: "are removed". Use the active voice. Sentence 39 uses the passive voice: "be merged". Use the active voice. | yes |
| warning | referee model | The headline states 64 blobs as a firm result. The other methods gave 65 to 67, and triangle gave 119. The report does not say which conclusions hold for all threshold methods and which depend on isodata alone. The count must be stated as method-dependent. | yes |
| warning | referee model | Triangle gives 119 objects, about 86 percent more than isodata. The log shows a median area of 21 pixels and 64 percent foreground for triangle. The report says it did not check why. It must not leave this outlier unexplained when it reports a range. | yes |
| info | referee model | The sizes 676, 858 and 902 pixels are not in the claim table. They do appear in the printed output of the run_script step, so they have a source. | yes |
| info | referee model | The statement that the count changes when small specks are removed rests on minimum-size runs made with Otsu. The report does not say these runs used Otsu, and it does not give the counts from them. | yes |
| info | referee model | The scientist asked the agent to check small objects in the outline picture. No logged step opened that picture. The agent used a script for the size check instead. | yes |
| info | referee model | The report gives scikit-image 0.26 as the library version. The log does not show the library version. | yes |
Numbers in the answer
The last claim check read 30 numbers in the answer. 27 numbers match a logged result. 3 numbers have no source in the record.
Numbers that do not match a logged result (3)
- no source in the record: - The five largest objects have areas of 658, 660, 676, 858 and 902 pixels.
- no source in the record: - The five largest objects have areas of 658, 660, 676, 858 and 902 pixels.
- no source in the record: - The five largest objects have areas of 658, 660, 676, 858 and 902 pixels.

Failed tool calls
No tool call failed.
Data integrity
Each data file has the same SHA-256 hash now as at the time of the step that read it. Where the download script (fetch.sh) gives a hash, the file also has that hash. The run did not change the data.
| File | SHA-256 | Fetched data | Steps with this hash |
|---|---|---|---|
{data}/schindelin2012-fiji-blobs/blobs.gif25.2 KB | 507d168e317a | same as the hash in the download script (fetch.sh) | n1, n2, n3, n4, n5, n6, n7, n8, n9, n10, n11, n12, n13, n14, n15 |
A SHA-256 hash is a fingerprint of the file contents. If one byte of the file changes, the hash changes. The table shows the first 12 characters.
How to repeat it
Get the data. The script downloads the files and checks their SHA-256 hashes where it lists them.
CUVETTE_DATA={data} bash bench/papers/schindelin2012-fiji-blobs/fetch.shRun the same case with Cuvette. The script gives the same answers from bench/papers/schindelin2012-fiji-blobs/bench.yaml.

setup The decision record starts with these values. A script set them before the first message, from the answers that we wrote before the run.
- Image channel to segment: graySource in the tutorial or test suite: The file is a single 8-bit gray image. The paper does not discuss it.
- Bright or dark objects: brightSource in the tutorial or test suite: Not in the paper. The file stores the blobs as high pixel values. An inverted lookup table (LUT) makes them look dark in ImageJ.
- Remove objects that touch the image border: falseSource in the tutorial or test suite: Not in the paper. We count edge objects. The count without them is an optional item.
- Split touching objects with a watershed: falseSource in the tutorial or test suite: Not in the paper. We use no watershed, so touching blobs can count as one.
- Pixel size: 0Source in the tutorial or test suite: The file has no spatial calibration. The paper does not discuss it.
- Unit of replication: images or fieldsSource in the tutorial or test suite: Not in the paper. There is one image, so no statistics across images apply.
harness note A note from the harness to the model. The scientist did not write it.
- Setup values: Design: - What is the unit of replication? (replication_unit): images or fields - Pixel size in micrometers (0 = uncalibrated) (pixel_size): 0 Segmentation: - Image channel to segment (stain_channel): gray - Are the objects bright or dark in that channel? (object_polarity): bright - Remove objects that touch the image border (exclude_border_objects): false - Split touching objects with a watershed (split_touching): false Ask the scientist: Threshold method (threshold_method), Smallest object to count (pixels) (min_object_size). The harness fills these values into your tool calls automatically. If you give a different value, the harness logs a deviation and shows it to the scientist. - Mode is now watch: you run the steps.

}comparison Comparison runs for Threshold method. The record keeps the scientist's choice.
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok
decision card Threshold method
The threshold decides which pixels are objects. Different methods can give different counts. The model runs the main methods and shows you the counts before you choose. The model wants to run count_objects.
Options: otsu li triangle isodata yen mean minimum
Suggested: otsu (The model proposed this value when it asked to run the step.)
Data that the model gave for this card
Threshold method n_objects Result otsu 64 ok li 65 ok isodata 64 ok triangle 119 ok n_objects depends on the choice: 64 with otsu, 65 with li, 64 with isodata, 119 with triangle
Answer isodata
No person answered in this run. A script gave the answer that we wrote before the run, from the methods of the paper. Source in the tutorial or test suite: Not in the paper. The ImageJ Default threshold is a variant of IsoData. We use the IsoData method of scikit-image as the nearest match.

decision card Smallest object to count (pixels)
Pixel groups with fewer pixels are removed before counting. Use 0 to keep all of them. Tiny groups are often noise and can change the count by a large factor. The model wants to run count_objects.
Suggested: 0 (The model proposed this value when it asked to run the step.)

}Model The model writes its answer. The claim check reads it. See the final answer.
The final answer
The model wrote this answer. The harness shows it to the scientist after the review.
The count_objects tool found 64 blobs in the image using the isodata threshold method. The smallest object size was set to 0 pixels, and the objects are bright in the gray channel. The threshold value was 124.7. The mean area of the blobs is 347.5 pixels. The results are saved in blobs_objects.csv, blobs_labels.tif, and blobs_outlines.png.
Settings and step results that the answer does not mention. The harness adds them.
Step results that the answer does not mention, from the record: - n1 inspect_image: 256 by 254 pixels, 1 channel(s), uint8, min 8, max 248 Settings used, from the decision record: Pixel size in micrometers (0 = uncalibrated): 0 · Image channel to segment: gray · Are the objects bright or dark in that channel?: bright · Threshold method: isodata · Smallest object to count (pixels): 0 · Remove objects that touch the image border: false · Split touching objects with a watershed: false.
Values that are not scored
- A trap value is the result of a wrong method, for example an unpaired test on paired data. A trap value in a main step means that the run used the wrong method. A trap value in a comparison run is correct, because the record keeps the scientist's choice.
- An optional value is a second result of the same method. The run can compute it or not.
- A reference value comes from a different program version or a check run by us. We show it for comparison.
| Item | Kind | Known value | Closest logged value | Tolerance | Outcome | Source of the known value |
|---|---|---|---|---|---|---|
particles_edges_excludedParticles, edge particles excluded. | optional | 46 | 44.58n10 count_objects | exact | in the record, outside the tolerance | We calculated it with ImageJ 1.53 (Default threshold, Analyze Particles with edge exclusion) |
Checks
Review findings
The review recorded 4 findings. A rule finding comes from a fixed check in the harness. A referee finding comes from a second model that reads the record. The harness shows the findings to the scientist with the final answer. The record does not mark a finding as fixed. Thus a finding from an early review round can apply to a draft that the model corrected later.
| Severity | From | Finding | Shown with the final answer |
|---|---|---|---|
| warning | ruleborder_objects_kept | Objects that touch the border are in the count. Report the count with and without them. | yes |
| warning | ruleno_size_filter | No size filter was used. Tiny pixel groups count as objects. Show the count at other sizes. | yes |
| info | ruletext_style | The answer breaks the text rules (ASD-STE100) in 2 places. Sentence 2 uses the passive voice: "was set". Use the active voice. Sentence 5 uses the passive voice: "are saved". Use the active voice. | yes |
| warning | referee model | The count varies significantly between threshold methods, but the report does not mention this variation. | yes |
Numbers in the answer
The last claim check read 4 numbers in the answer. 4 numbers match a logged result. 0 numbers have no source in the record.
Deviations
The model did not try to change a choice of the scientist.
Failed tool calls
No tool call failed.
Data integrity
Each data file has the same SHA-256 hash now as at the time of the step that read it. Where the download script (fetch.sh) gives a hash, the file also has that hash. The run did not change the data.
| File | SHA-256 | Fetched data | Steps with this hash |
|---|---|---|---|
{data}/schindelin2012-fiji-blobs/blobs.gif25.2 KB | 507d168e317a | same as the hash in the download script (fetch.sh) | n1, n2, n3, n4, n5, n6, n7, n8, n9, n10 |
A SHA-256 hash is a fingerprint of the file contents. If one byte of the file changes, the hash changes. The table shows the first 12 characters.
How to repeat it
Get the data. The script downloads the files and checks their SHA-256 hashes where it lists them.
CUVETTE_DATA={data} bash bench/papers/schindelin2012-fiji-blobs/fetch.shRun the same case with Cuvette. The script gives the same answers from bench/papers/schindelin2012-fiji-blobs/bench.yaml.
