Hi,
Unless you have very bad bias field BET should not require bias field
correction before running. If you do then the recommended route is to
run BET, run FAST-based bias-field correction (saving the bias field
output), dilate the bias field with avwmaths, apply this to the
original, and then re-run BET.
Cheers.
