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
fmriprep version 23.1.4
Using Docker via apptainer on a supercomputer, but this error also appeared on my personal computer (while also using Docker)
Yes it is BIDS validated.

jumping ahead a few lines to the series of Tracebacks
nipype.pipeline.engine.nodes.NodeExecutionError: Exception raised while executing Node gen_avg.
File "/opt/conda/envs/fmriprep/lib/python3.10/site-packages/traits/base_trait_handler.py", line 74, in error raise TraitError( traits.trait_errors.TraitError: The 'oned_matrix_save' trait of a VolregOutputSpec instance must be a pathlike object or string representing an existing file, but a value of '/home/cb3/amango/work/fmriprep_23_1_wf/single_subject_29_wf/func_preproc_ses_1_task_face_run_8_wf/bold_std_trans_wf/bold_reference_wf/_std_target_MNI152NLin2009cAsym.resnative/gen_avg/vol0000_xform-00000_merged_sliced.aff12.1D' <class 'str'> was specified. During handling of the above exception, another exception occurred:

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.
