just to add to Mark's comment:
the only difference would be non-fat saturated EPI where you see more non-brain tissue but most commonly fat-sat is used.

Betreff: Re: [FSL] registration question
This isn't normally a problem as most EPI images show
very small amounts of non-brain matter by comparison
with structural images. You can always check how much
of an impact it makes by running bet on the example_func
and then registering it to the structural (with flirt)
and comparing the results. I don't expect it to make
All the best,
