Thanks bruce for your response. I am trying to expand the pial surface (see attached image) in order to estimate the GM/WM boundary properly. I have successfully expanded the white matter but when i tried the mris_expand scripts for pial surface (mris_expand -thickness lh.pial 0.5 lh.newpial), the output looked identical to the input. Please can you direct me on how to successfully achieve this for the pial surface and how to incorporate my changes (expanded surfaces) into recon-all. Thanks. Best, Paul
