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
, but I'd prefer
to edit that after the surfaces are created.
Thanks again!
