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
