Re: [Freesurfer] Failed to load surface

Hi, Those aren't surfaces - they are scalar fields over surfaces. You can visualize them by first loading any surface you want (e.g. lh.inflated), then use the "load curvature" or "load overlay" functions in freeview to visualize them on the surface. Cheers Bruce From: freesurfer-boun...@nmr

Re: [Freesurfer] Failed to load surface
