External Email - Use Caution Thank you for responding. So before you responded, I tried a few things out. one of them was to make the edit to the image and then run recon-all with "-autorecon2-noaseg -autorecon3". I found this to move the surface however the aparc+aseg file had the voxel I altered as 247. Last night I tried what you suggest with the same alterations to the aseg.presurf file, I found the surface and aparc+aseg was unchanged.
