fMRIprep suddenly giving error code: 10 - REPETITION_TIME_MUST_DEFINE but the TR is already defined

Summary of what happened:

I have been preprocessing a dataset with fMRIprep, and did this successfully for the first 11 subjects. However, last week, I launched fMRIprep for the next 5 subjects, and the first three ran and have now finished successfully, but the last two failed, with errors in the logs that the Repetition Time is not defined, as well as warnings that the slice timing is not defined. I now cannot get fMRIprep to run for any participants. But when I check their .json files, the ā€œRepetitionTimeā€ and ā€œSliceTimingā€ fields are defined. I have compared them carefully to the .json files for subjects that ran successfully before this problem occurred, and they are exactly the same (aside from the acquisition time). Iā€™m stumped about what could be going wrong, especially since nothing seems to have changed between the subjects that already ran successfully and all the rest of them. I would greatly appreciate any ideas! More details about what Iā€™ve tried and noticed in the Screenshots/relevant information section.

Command used (and if a helper script was used, a link to the helper script or the command generated):

I believe what I used is a helper script, so here is an example of the command generated by it:

 sbatch --no-requeue -n 1 --mem=100000 --time=40:0:0 --cpus-per-task=12 --job-name="sub-035_fmriprep" --output=/proj/lindquistgiovanello/projects/EPIC/logs/FMRIprep_logs/Output-sub-035_fmriprep-jobid-%j.out --wrap="unset PYTHONPATH; export SINGULARITYENV_TEMPLATEFLOW_HOME=/proj/hng/singularity_imgs/template_flow; singularity run -B ${TEMPLATEFLOW_HOME:-$HOME/.cache/templateflow}:/proj/hng/singularity_imgs/template_flow,/proj,/pine,/work,/nas02,/nas -e --no-home /proj/hng/singularity_imgs/fmriprep_1.5.3.sif /proj/lindquistgiovanello/projects/EPIC/data_BIDS /proj/lindquistgiovanello/projects/EPIC/data_fmriprep/fmriprep participant --participant-label 035 -w /work/users/n/g/ngfrye --fs-license-file /proj/hng/singularity_imgs/license.txt --nthreads 12  "

Version:

fMRIprep version 21.0.2, but have also tried with version 22.1.1 and version 1.5.3 with the same results.

Environment (Docker, Singularity, custom installation):

Iā€™m a bit new to this and Iā€™m not totally sure what this means, but I believe Singularity. Iā€™m running fMRIprep through an fMRI processing pipeline that we use at my institution called clpipe. So it runs on an HPC, and it implements fMRIprep for preprocessing.

Data formatted according to a validatable standard? Please provide the output of the validator:

The data are in BIDS format. Some context on that in the relevant information section below - in short, I am working from niftiā€™s rather than DICOMS and manually created .jsonā€™s and put the data into BIDS format. Once I did this for one subject, I ran BIDS validator to check that it worked, and got the following output:

Background info on the data:

There are only niftiā€™s for these data, no DICOMS, so I have had to find a way to get the data into BIDS format to be compatable with fMRIprep and with my institutionā€™s processing pipeline. Here are the steps I have done to do that: I created .json files for each task, using .jsonā€™s from another study as a template and filling in all the needed metadata, which I do have access to. I created a BIDS file structure and moved the niftiā€™s into the proper folders, renamed them according to BIDS conventions, and uploaded the .jsons to accompany them, aslo naming them according to BIDS conventions. Then, for the .jsons accompanying functional runs, I opened each and edited the ā€˜AcquisitionTimeā€™ field according to study records, and sometimes changed the ā€˜SeriesNumberā€™ if the study records indicated the protocol was adjusted in a particular scan and tasks were re-ordered. The .jsons for the structural runs I was able to get straight from Flywheel where they were automatically generated (unlike our functional runs), so I didnā€™t change anything about them and just moved them into the appropriate folders. After doing that and running BIDS validator, there was an error indicating that the nifti headers on our functional runs did not contain the units for the TR or voxel dimensions, so I opened and edited each functional nifti header using flsedithd and adding those fields. After doing this, BIDS validator ran without errors, and I was able to process the first 11 participants with fmriprep.

Other notes:

On the first subject that failed, these errors/warnings pointed to only the last 4 tasks, and on the second subject that failed and all other subjects I have tried since, it points to all tasks.

I have also checked the nifti headers, and they are exactly the same as those for subjects that already ran successfully. When I ran BIDS validator again, it now shows a number of additional errors and warnings that similarly donā€™t make sense to me, such as needing to define ā€˜TaskNameā€™ for the file, when it is also defined in all of the files and is the same as in the .jsonā€™s for subjects that ran successfully. I also see in the BIDS validator output that it is not giving errors/warnings for the subjects that already were ran successfully, even though I canā€™t find anything thatā€™s different about them.

I have tried using different versions of fMRIprep, as well as different versions of the pipeline I am using to implement it (clpipe)

Hi @ngfrye and welcome to neurostars!

Please share an example JSON for your BOLD images that is failing.

The difference in BIDS validation outputs could be from different versions of the validator. You should use the most recent version available, or at the earliest, the version included with the fMRIPrep version you want to use (which should probably be the most recent fMRIPrep version, 23.1.3 at this time).

Best,
Steven

Iā€™ll check which version of BIDS validator Iā€™m using, it looks like it might be an older one so I might need to adjust that. In the fMRIprep output at least it looks like both were using BIDS validator 1.8.0.

Hmm, this looks fineā€¦ what happens if you --skip-bids-validation?

Aha, that seems to be getting somewhere ā€“ itā€™s running now and has created a folder in /fmriprep for the subject and a figures folder, when before it failed within a minute or two and never created a new directory. It usually takes about 24hrs to run fully for this study so Iā€™ll have to check back tomorrow afternoon to see if it actually completed successfully and if the output looks right, but fingers crossed!

It looks like the subject ran through fmriprep successfully! Iā€™m not sure whatā€™s going on with the bids validation but this seems to work as a workaround and the fmriprep output looks good. Thank you!
