The output of fmriprep is incomplete

[WangYunHong98]

What happened?

I used fmriprep-24.0.0 on slurm to process my MRI data, but the outputs were incomplete.

For example, freesurfer directory was empty and the output of --output-space I specified was not produced in the func and anat directory.

I uploaded the log file. Please check it out fmriprep-30459_6.json

There's either a permissions issue or a concurrency issue. Are you running multiple subjects simultaneously with the same FreeSurfer directory?

[WangYunHong98]

Hi @effigies

I possibly run multiple subjects because I submitted the slurm job using this code sbatch --array=1-$(( $( wc -l ${PROJECT}/BIDS_heudiconv/participants.tsv | cut -f1 -d' ' ) - 1 ))%20 fmriprep.slurm

[effigies]

So what's happening is that you have an fsaverage directory from an older version of FreeSurfer. To keep FreeSurfer working correctly, we delete and replace with the bundled copy. If you have multiple copies of fMRIPrep doing this at the same time, you will get race conditions.

There's no real plausible way to protect against this in code. It's up to users not to call fMRIPrep in parallel in this situation.

[WangYunHong98]

Hi @effigies

It occurs an error later. ERROR: Label BA1_exvivo does not exist in SUBJECTS_DIR fsaverage! The fsaverage link probably points to an older freesurfer version

This error is very strange. Sometimes I'm running fmriprep and I don't get this error, sometimes I run it and it keeps coming up. Is there any way to fix this? For example, submit a job first. After this job is completed, I submit the parallel array job.

[tsalo]

That sounds like a recurrence of the other issue you opened: #3258.

[WangYunHong98]

@tsalo

Yes, it's an old problem. I tested it, and if I submit a job array for one subject, fmriprep (version-24.0.1) runs successfully with doing surface reconstruction. But if I submit a job array for multiple subjects, I get the error I mentioned above.

By the way, the --containall was added to the script.

So, I'm ready to try this way: --fs-subjects-dir /output/freesurfer/$subject -w /work/$subject Prepare seperate directories for each subject.

But I'm not sure it's the right thing to do. What do you think? @effigies
