the fix is to acquire a FLAIR or T2 image. What you are seing is the
tentorium of the cerebellum which is very difficult to distinguish from
cortical gray matter on a T1-weighted image. If you don't have either of
those datasets you probably will need to do manual editing Bruce

Sorry!
The attachments are really showing the same structure, but in different
views. I have at least a hundred slices which include it. Since the pial
surface is not extending into cerebellum, should I just edit brainmask.mgz?
Is there a quicker fix to the problem than manual editing?
Thank you very much!
Sincerely,
Ye

what do you mean by the structure in the circle? The circles are
pretty big and have a lot of WM and GM in them.

Dear Doug,
Thank you very much!
Are you basically saying that the structure in the circle
is not part of the cortex?
