Does it affect the aseg with respect to the GCA registration? Is so, how perfect does the strip need to be to avoid biasing the aeg results, eg., are small portions of the meninges or skull around the top of the cortex going to affect the results much? I now they can affect the pial surface, but I'd prefer to edit that after the surfaces are created. Thanks again! Alex

if the strip removes the cerebellum, then the aseg stuff will fail (if you're using it). If you aren't it doesn't really matter.
cheers, Bruce

Hi all, Couple of questions re: failures of skull stripping"
- If you edit the brain volume after autorecon1, do you need to re-run autorecon1 again, or van you just continue on to autorecon2?
- Is it a major problem if the strip removes the cerebellum, since it's excluded by the cuttting planes anyway, or does this interfere with finding the cutting planes later on?
Thanks, Alex
