Doug, Freeview looks like the best way to get what I want. Still trying to figure out how to mark a point in the 3D viewing window, but at least when I mark them in the 2D windows I get all the coordinates I need.

One way around it is to find the vertex number, then find the RAS for that vertex by converting the surface to ascii. freeview might do a better job than tksurfer. doug On 01/03/2013 10:38 PM, Jeff Eriksen wrote: FreeSurfer experts, I am trying to mark points on a surface in tksurfer, then obtain their original voxel coordinates.
