Hi,
I encountered an error ‘Node split failed to run on host d8e02eaca1d2’ while running fMRIPREP.
The issue seems to be directly relevant to one of the Python scripts ‘genericpath.py’ where it fails to read paths to all EPI files from _phasediff.json for distortion correction.
I’ve converted raw DICOM to NIFTI using HeuDiConv and manually inputed ‘IntendedFor’: [‘path/to/file,’ ‘path/to/file2’, …] in each phasediff.json file. All subject directories passed bids validation.
I couldn’t find any error reports similar to this one, so I’d really appreciate if someone can help me solve it.
Below is the error log:
Node:fmriprep_wf.single_subject_00001_wf.func_preproc_ses_01_task_prl_run_02_wf.sdc_estimate_wf.phdiff_wf.split
