Dear FSL experts,
We have run into some registration issues in FEAT. For a handful of participants (most cases are fine), the fieldmap and highres images are severely misaligned. see here: https://www.koumurayama.com/experiments/GF/Pictures/Screenshot_fieldmap.png
These participants' func_to_standard registrations are poorer than other participants so we believe this may be what is driving the difference.
We have used the fmap_rads image and mag_brain images in the b0 unwarping tab in FEAT - as instructed on the fsl wiki.
We were wondering if there is a possible solution to this problem. It seems strange that it is only occurring in a small subset of participants.
Any advice you can give would be very helpful. Happy to provide any files you need.
Many thanks,
Carolyn and Greta
