Hi Alexander

this is probably best done by running tksurfer and tkmedit simultaneously. You can save point in tkmedit and goto point in tksurfer to find the vertex. Or you can do it in freeview, which will display the vertex directly (or you can use tkmedit->tools->find nearest vertex)

Hello all,

I segmented a brain with FreeSurfer and I am very satisfied about the result. After that I visualized the T1.mgz together with the white surface in TkMedit. Now I am looking for interesting anatomical structures. My goal is to assign vertices in the white surface at the corresponding points and save the coordinates or better the index of the vertices. Later I will use the selected vertices in Matlab. I already read the surface with <freesurfer_read_surf.m>.

Do you have a good procedure to do that? I appreciate any hint.

Thank you so much in advance.

Sincerely,

Alexander
