[Errno 39] crashes with (potentially) freesurfer

Summary of what happened:

Hi! When running fmriprep on my data, it crashes at some point during processing anatominal run. From the error message in the log file, it says OSError: [Errno 39] Directory not empty: 'label'
At first I thought it means the /label folders inside of /fmriprep/sourcedata/freesurfer should be empty, so I deleted the whole freesurfer folder and reran it. It still show this error. Wierd thing is at the end of the log file (attached below), it says run successfully. While in the output there is only sub-007_desc-preproc_T1w.nii in the /anat folder, without the /func folder.

I’m running with --ignore fieldmaps, but it also happen when running with fieldmaps.

Here is the output file in HPC. Hope it helps. I can’t really understand where it goes wrong from these output messages. Hope you can help me figure out what should I do. Many thanks!

Hi @hanqiuishere,

Can you try doing the following?

  1. update to 22.1.1 (most recent at this time)
  2. try specifying a fresh work directory with the -w argument.
  3. make sure no pre-existing Freesurfer outputs are being used
  4. if you can, try using a container (Docker or Singularity) to run the workflow. Using your own anaconda environment introduces the possibilities of different software versions being used. Of note, recent versions of fmriprep expect FreeSurfer 7.2 so they may not work with earlier versions.

Thanks,
Steven

Hi Steven,
Thank you very much for the suggestions!

It is already ran in a container. Most importantly, these data have been run successfully before with fmriprep 22.1.0 and freesufer 7.3.2, so these might not be the problem. I also noticed some new information, could you have a look at if it help to locate the error?

The error message above is from sub-007, which was newly added and never been processed with fmriprep before. However, for the other subs, which have been run before (but I deleted the whole bids folder before re-running them), the error is different:

here is the full log
fmriprep_sub-005.o48433627.txt (2.4 MB)

Besides, after running, in the bids/derivatives/fmriprep/sourcedata/freesurfer folder, sub-007 (the new one) is missing.
I guess the new sub broke at an earlier stage than the ones that have been run before. But still even for the new one (which for sure has no previous freesurfer output) it didn’t work.

Could you perhaps tell more from this? I really appreaciate any help. Thanks!

Hi,

The text log you attached is using fmriprep 22.0.1. I am confused as you said you were using 22.1.0. If different versions are mixed using the same work directory that can lead to problems.

Please (1) update to the newest version (22.1.1 at this time). (2) provide the full command you use to run fmriprep (including the docker run or singularity run arguments), making sure to specify a work directory that has not been used. (3) make sure there are no pre-existing Freesurfer outputs that fMRIprep can be using.

Also, can you confirm that the only bids validator output was the events.tsv warning?

Best,
Steven

Hi Steven,

Thanks a lot!

I got new results: using a newly created folder as working directory, and tried with both 22.1.1 and 22.1.0, the results are the same: Now some subjects are running successfully, while two subs still get the same error as before (the first one in this stream)

for (3):
I deleted the whole /sourcedata/freesurfer folder before rerunning it, and also changed the output directory of fmriprep. Can this make sure no pre-existing Freesurfer outputs that fMRIprep can be using?

It’s really good that with a working directory some subs run well, but this also makes the problem more confusing, since the subs were handled in the same way. Could you think of other possible reasons? Really appreaciate any help! Thank you!

Hi,

Glad that some subjects are working!

For the subjects that do not work, was it the same subjects that were failing before? If you repeat the process with these two subjects (e.g., delete their freesurfer data, restart job with new working directory), does it still fail? What is in the contents of these subjects’ label folders?

Deleting the data in sourcedata/freesurfer should do the trick, as that is the default place fMRIPrep will look for freesurfer outputs.

Your command looks fine, but I note two things. First, I would add a bind string to the singularity part of the command, e.g.,singularity run --cleanenv -B /FULL/PATH/TO/bids --env ...... The second would be that I would not put have a separate output directory for each subject, which you seem to be doing here based on your output directory being called bids/derivatives/fmriprep_sub001007. I also imagine this could just be something you are doing while testing, but just make sure that when you are ready to run for real, that your output directory is just bids/derivatives.

Best,
Steven
