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.
