Hi,
sorry, I should have been more specific... It can be
run in parallel if your lab has got a SGE system or
something like that (sorry I'm not very good at these
things) and then you send your job to a bunch of
computers involved in the cluster. It should not take
much longer anyway.
Hopefully, we should get a better and much quicker
non-linear registration (FNIRT) soonish and that will
be included in the next FSL4.1 patch.
Cheers,
Gwenaelle
