Summary of what happened:
Hi, prefacing this that I am very new at this and I don’t think this has been posted already. I’m using fMRIprep on one participant, and haven’t gotten it to work yet. The participant has one anatomical and 8 functional bold runs. Everything seems to be working until the gen_avg node is set up and run. Then, 3dVolReg from AFNI has a fatal error. After this error, gen_avg finishes, but it stores the result file without outputs. Right after, there’s an error on the file path leading to gen_avg. The traceback indicates that a trait of VolregOutputSpec must be path-like or string, but the value was something else. Then, while handling this, another error occurs: FileNotFound. More details in the log below.
Command used (and if a helper script was used, a link to the helper script or the command generated):
apptainer exec docker://ashleymango/fmriprep fmriprep /work/cb3/amango/Nifti /work/cb3/amango/derivatives participant --participant_label 29 --fs-no-reconall --fs-license-file $WORK/license.txt -w /home/cb3/amango/work1
Version:
fmriprep version 23.1.4
Environment (Docker, Singularity, custom installation):
Using Docker via apptainer on a supercomputer, but this error also appeared on my personal computer (while also using Docker)

Screenshots / relevant information:
This problem occurs with each run of fmriprep, for the gen_avg in the bold_t1_trans and the bold_std_trans folders. It’s not always the same file not found though. Once it was the vol0000_xform-00000_merged_sliced_md.1D’ that was not found for output ‘md1d_file’ of a Volreg interface.
Thanks in advance! Really trying to make this work. Please let me know if I should explain more.
