T1.mgz was not found when re-running failed freesurfer preprocessing

fmriprep

#1

I tried to preprocess data from one participant but Freesurfer failed. Before re-running the preprocessing, I deleted the subject-specific folders in preprocessed/fmriprep, preprocessed/freesurfer and the work_dir/fmriprep_wf. Then I encountered the error message attached below. My guess is that I didn’t delete all files storing preprocessing progress. More generally, I was wondering what is the best way to let fmriprep re-preprocess one subject from scratch? Thanks a lot!

What is the command line you are running?

I’m under the impression that you did not remove everything about your subject under the work directory.

If you anticipate that you will need to re-run subjects in an agile manner, but keeping the intermediate results of other subjects that you call “finished”, then I’d create a work directory specific to each participant:

singularity run /share/PI/russpold/singularity_images/poldracklab_fmriprep_1.0.8-2018-02-23-8c60ec5604ac.img $SCRATCH/CCD $SCRATCH/CCD/preprocessed participant --participant_label sub-18 --output-space T1w template -w work/sub-18

Please note the added -w work/sub-18 bit. This way, if you want to re-run participant 18 you would delete the following folders $SCRATCH/CCD/preprocessed/{fmriprep,freesurfer}/sub-18 and work/sub-18.

Changing the work directory solved the problem! Thanks!
