Hi,
I would like to do an unwarping of an Epi measurement. Our fieldmap
aquisition sequence gives us a magnitude image and an unmasked real
field map image. If I then use Prelude and the B0 unwarping option in
Feat, it's the Flirt registration that terribly fails. So far I
accounted that to the unmasked real field map, which is very "noisy"
outside the brain/skull. Is there a way to create an appropriate mask
with FSL?
regards,
Renate
