it all depends on what surface you are looking at. I think tksurfer reports coords for the ?h.orig

Hi Idil
we keep track of different kinds of RAS coordinates, which may not be the same (surface ras, scanner ras, etc...). cheers Bruce

Hello FS experts,
I am wondering if anyone knows why the same vertices' coordinates are shown slightly different when opened in freesurfer and tksurfer. I was checking some annotation files for each subject across the two on inflated surface, and noticed slight coordinate differences in RAS. ex. freesurfer vertex 2407 [-18.23, -78.84, 27.92] ----- tksurfer vertex 2407 [-18.48, -78.82, 28.23]
