Susceptibility distortion correction not performed in fMRIPrep

My preprocessing summary reports all say: Susceptibility distortion correction: None
but I have fieldmap scans–and I don’t see a configuration setting for fieldmap sdc
Grateful for any help!!

Do your fieldmap JSON files have IntendedFor fields to associate the fieldmaps with the BOLD files?


no sir, they don’t–is this something Flywheel needs to correct, or is there a way to modify this on my end?

This is something you would need to correct on your end. You can add them manually to the files (or make a script to do this, see below for a quick example I made in python).
