Hi Ruopeng,
Do you know if freeview has a way to show the selected point on the 3D surface? Double-ckicking in the 3D window seems to choose the point I want on the 3D surface (projecting perpenducularly from the 2D screen to the underlying scalp surface point) and displays a red cross in the 3 2D views, but it show nothing in the 3D window.
Thanks, -Jeff

Hi Jeff I'm not sure you can, but Ruopeng would know. If not, we can add it to the FreeView feature request list.

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.
Thanks, -Jeff

tksurfer may be putting all 0s in the RAS field because the head surface does not match the cortical surface (tksurfer is very inflexible in this way). 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.

Can you cc the list so others can answer? Freeview can rotate....
