that's true, but if the white matter surface is already correct you can change some of the intensity bounds in mris_make_surfaces. The automatically calculated ones will be in the recon-all.log and you should check them before changing them

Hi there
To my understanding, if you want to edit the pial (push it outwards more) then you need to edit the white matter, as the pial is made from the white matter surface. You can do this by manually extending the white matter surface and re-running your surfaces.

In some subjects, the pial surface border is somewhat narrow (within the border of graymatter in my view) although there is no skull stripping error. I heard that adding the control point might extend the border of graymatter as well as that of white matter from other researcher. Is it true? Or, is there other way to edit to extend the pial surface border?
Thank you.
Best, Seung-Gul
