Hi Chris,

Thanks a lot. I agree that control points should actually only be put in white matter. I'm just not sure if I can expand the pial surface to a satisfactory extend if I only do edits in the white matter. It seems to me that the problem here is that the signal weakened in the lower part of the brain so that the gray matter doesn't have adequate intensity to be included in the pial surface (the values are around 30).

Thanks, Cherry

Dear FS experts,

I have a subject where large portions of temporal lobe is not included in the pial surface. A member in my lab has suggested edits on brain.finalsurfs.mgz. However, in the following page it is indicated that edits on brain.finalsurfs.mgz is only intended for cases regarding inclusion of cerebellum. Can anyone please let me know which volume I should be working on in this case?

Hi Cherry

Chris is right. Putting control points in the WM will help the pial surface as well.

cheers Bruce
