Thanks, Steven! We originally thought our registration was failing because we are analyzing task data and our task vs. rest activation maps weren’t perfectly aligned with the edge of the brain, as expected. We thought this might be caused by the functional and anatomical brain masks not aligning perfectly. I’m now wondering if re-running fmriprep with synthesized fieldmaps may help this issue. I tried following the method you outlined here.
Do these fieldmap corrected outputs from fmriprep seem reasonable to you?
Thank you!
