Errors reported incorrectly when handling too many files

[mateuszpawlik]

I'm executing BIDS Validator v1.14.8 on a large dataset (~800GB, ~4500 files). The validator reports incorrectly the following errors:

• [ERR] You have to define 'RepetitionTime' for this file. (code: 10 - REPETITION_TIME_MUST_DEFINE)
• [ERR] You have to define 'EchoTime1' and 'EchoTime2' for this file. (code: 15 - ECHO_TIME1-2_NOT_DEFINED)
• [ERR] You have to define 'TaskName' for this file. (code: 50 - TASK_NAME_MUST_DEFINE)

These values are present in the JSON files.

It seems that the validator doesn't consider the JSON files. Is it possible that I reach some limit. It's not memory because the validator executes and finishes.

When I bidsignore half of the subjects, the validation passes.

I'm happy to do more investigation but I'd need to know what.

[mateuszpawlik]

I understand that legacy validator may be of lower priority, but is there anything I can do to fix this?

[effigies]

I personally don't have any notion how to start investigating this. Are you also seeing the issue with the schema validator?

[mateuszpawlik]

If you mean the Deno based validator, I'm planning to execute it. I'm fetching the data now. Once I do it, I will report, but possible next week. Thanks.

[mateuszpawlik]

I've tried the Deno validator. It also reports weird issues for most of the files, which should not be reported. I checked some of the reported files manually and there should be no issue.

I used this command:

docker run -ti --rm -v $PWD:/data:ro denoland/deno deno run --allow-read --allow-env https://deno.land/x/bids_validator@v1.14.8/bids-validator.ts /data

• [WARNING] NIfTI file's header field for dimension information is blank or too short. (NIFTI_DIMENSION)
• [WARNING] NIfTI file's header field for pixel dimension information is empty or too short. (NIFTI_PIXDIM)
• [WARNING] A data file's JSON sidecar is missing a key listed as recommended. (SIDECAR_KEY_RECOMMENDED)
• [ERROR] Repetition time did not match between the scan's header and the associated JSON metadata file. (REPETITION_TIME_MISMATCH)
• [WARNING] You must define 'EchoTime' for this file. 'EchoTime' is the echo time (TE)
  for the acquisition, specified in seconds. (...)

I also get "[WARNING] The onset column in events.tsv files should be sorted. (EVENT_ONSET_ORDER)". My guess is, that this is because we have negative onsets at the beginning.

The number of files seems to be reported correctly in the summary of both validators: 4428 Files.

Update: These issues show even if I bidsignore all subjects but one.

[mateuszpawlik]

We had some invalid json files in the dataset. We new about them. Fixing them caused the legacy validator to work more as expected, not reporting the errors, which I listed originally. It did not help the issues reported by the Deno validator.

It seems that something is happening internally, which causes throwing other errors when some json files are invalid. I remember reading about similar issues. Are there maybe any errors set by default and reported when something else breaks?

docker run -ti --rm -v $PWD:/data:ro denoland/deno deno run --allow-read --allow-env https://deno.land/x/bids_validator@v1.14.8/bids-validator.ts /data

We've been making a bunch of fixes in the last week or so since that release, so can you re-test with:

deno run --reload -A https://github.com/bids-standard/bids-validator/raw/master/bids-validator/src/bids-validator.ts?

* [WARNING] NIfTI file's header field for dimension information is blank or too short. (NIFTI_DIMENSION)

This means that either dim[0] == 0 or min(dim[1:dim[0]]) <= 0. If that's not the case, that's a bug. If you could share the NIfTI header, I could test this. Simplest way to share:

python -c "import sys, nibabel; print(nibabel.load(sys.argv[1]).to_bytes()[:348])" <PATH>

* [WARNING] NIfTI file's header field for pixel dimension information is empty or too short. (NIFTI_PIXDIM)

min(pixdim[1:dim[0]]) <= 0

* [WARNING] A data file's JSON sidecar is missing a key listed as recommended. (SIDECAR_KEY_RECOMMENDED)

This is almost impossible not to have, and a result of the schema validator systematically reporting RECOMMENDED sidecar fields. It's going to be noisy because BIDS has a lot of these, but they've only been selectively applied in the legacy validator. (Preview: I'm going to be advocating for reducing many fields to OPTIONAL.)

* [ERROR] Repetition time did not match between the scan's header and the associated JSON metadata file. (REPETITION_TIME_MISMATCH)

This could be a rounding problem: https://github.com/bids-standard/bids-validator/issues/2091

* [WARNING] You must define 'EchoTime' for this file. 'EchoTime' is the echo time (TE)
  for the acquisition, specified in seconds. (...)

This is a problem in the schema, I'm going to submit a patch today.

I also get "[WARNING] The onset column in events.tsv files should be sorted. (EVENT_ONSET_ORDER)". My guess is, that this is because we have negative onsets at the beginning.

This is surprising. I've just checked the sorting function and it should handle negative numbers fine. Would you open an issue with a failing file?

[mateuszpawlik]

Now I'm getting the following error with the legacy validator, which doesn't make sense to me, because why the json files in phenotype directory should be validated against a schema and have the listed properties.

[ERR] Invalid JSON file. The file is not formatted according the schema. (code: 55 - JSON_SCHEMA_VALIDATION_ERROR)
                ./phenotype/ASR.json
                        Invalid JSON file. The file is not formatted according the schema.
                        Evidence:  should have required property 'PixelSize'
                ./phenotype/ASR.json
                        Invalid JSON file. The file is not formatted according the schema.
                        Evidence:  should have required property 'PixelSizeUnits'

That looks like it's being picked up by a microscopy rule.

I don't know about that, but I've only been tangentially involved in the legacy validator. @rwblair might remember something here?

[mateuszpawlik]

That is weird but thank you. Renaming the file resolves this issue but it's not really a solution.

Damn. Okay, apparently that method was disabled by #2077. Use https://github.com/bids-standard/bids-validator/raw/deno-build/bids-validator.js.

This problem we actually found in our data 🙈

        [WARNING] ECHO_TIME_NOT_DEFINED You must define 'EchoTime' for this file. 'EchoTime' is the echo time (TE)
for the acquisition, specified in seconds. Corresponds to DICOM Tag
0018, 0081 Echo Time (please note that the DICOM term is in milliseconds
not seconds). The data type number may apply to files from any MRI modality
concerned with a single value for this field, or to the files in a file
collection where the value of this field is iterated using the echo entity.
The data type array provides a value for each volume in a 4D dataset and
should only be used when the volume timing is critical for interpretation
of the data, such as in ASL or variable echo time fMRI sequences.

The NIFTI header warnings are not there anymore.

We are aware of some of the issues but some seem not right:

• [WARNING] SIDECAR_KEY_RECOMMENDED - especially these reported on *events.tsv files
• [ERROR] REPETITION_TIME_MISMATCH - I will check the values
