traits.trait_errors.TraitError: The trait 'out_files' of a SplitOutputSpec instance is an existing file name, but the path '[redacted path 2]/work/fmriprep_wf/single_subject_01_wf/func_preproc_task_ambigfig_run_2_wf/bold_split/vol0000.nii.gz' does not exist.
This error is a potential duplicate of #936, and may also be related to nipy/nipype#2380.
First of all, I would really appreciate that you provided the contents of the file at the beginning, where it says "Saving crash info to...", so this file -> [redacted path 1]/output/fmriprep/sub-01/log/20180723-131939_b51df0ea-fdb1-4218-9555-cd6e12a8271d/crash-20180723-134502-kehg3633-bold_split-7619f81e-d7f6-472f-9a4c-8937d6c6f643.txt
I can see that the output path [redacted path 1]/output/``` is different, but similar to the working directory ([redacted path 2]/work). Please check whether either [redacted path 1]or[redacted path 2]`` are real paths (i.e. they are not just links).
Finally, what do you see if you run:
ls [redacted path 2]/work/fmriprep_wf/single_subject_01_wf/func_preproc_task_ambigfig_run_2_wf/bold_split/
(please remember to replace the [redacted path 2] bit with the path you have in your logs.
