Hi - I presume you mean that you have wraparound? If the wraparound of the edges of the brain is not overlapping then I suggest cutting and reordering chunks of your data with fslroi and fslmerge. Otherwise, if it is badly overlapping yes you can try BET but this will not be able to fully clean up your data - you would need customised analysis to try to clean up the overlap, but it won't be easy.... Cheers.
