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
