Hi Octavian

sure, define a sagittal cutting plane in tksurfer, or in matlab set ripflag=1 for all vertices with the x coord > 0 (or < 0)

Dear all,   Is there a way to crop a surface in FS, freeview or matlab? I have the inner_skull_surface in BEM folder, and I want to see just the right half, akin to cropping along the A (RAS) axis from the left. This is in order to visualize the inside of the surface with some electrode applications. Also, if the surface can be created in MNE just on the right side that will solve it. Help much appreciated, Octavian Lie.
