oh, I wouldn't worry about the surfaces in the hippocampus. They aren't meant to be accurate there. There is too much internal structure there - we model is separately in the aseg.mgz files.

Dear, Dr. Fischl Thank you for your suggestion. My problems are around hippocampus. The grey/white surface is OK now. but some grey matters are not included in the pial surface. How to change the Pial surface? Thank you again,
Xin

it depends why it's not getting out far enough. Usually you need to add control points in the nearby white matter that are <110 on the brainmask.mgz volume.

Hello, Group
I need to edit the pial surface. I learned to remove points with tkmedit from the tutorial. But how to add gray matter in the pial surface?
Thank you in advance.
