RuntimeError: EchoTime2 metadata field not found

Glad it worked! Although I’d suggest you to double check the results because I’m doubtful about how fMRIPrep will digest those multi-echo EPIs.

I’d really appreciate you helped me debug this problem with the phase-difference method. Going back to your examples, I see that the failure happens with the field map on session 002. However, the JSON file you posted corresponds to session 001. I wonder whether the information is missing for session 002 only. Could you check on that json?

Would you mind also posting /vols/Scratch/gspitz/gut_study/data/fmriprep_wd_15/fmriprep_wf/single_subject_018_wf/func_preproc_ses_001_task_faces_echo_1_wf/sdc_wf/phdiff_wf/meta/_report/report.rst?


Attached are the phasediff reports from both ses001 and ses002.

With regards to the epi SDC methods, I have one reverse phase epi image for each echo time. I include the IntendedFor to link the reverse phase epi with the correct image. Looking at the html report, it seems as though a correct was applied successfully. Is there a better way to check this?

Kind regards,
