Hi all:
     I am studying the coordinate system transforms within subject across imaging modalities on web page:
http://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems. I met a problem. First, i run tksurfer : tksurfer subjectname lh inflated -reg register.dat -ov mov.nii , then i chose a point on the surface and save it. There would be Vertex Index value and Vertex RAS value on the panel of TKSurfer Tool. For example:
                               Vertex Index       96063
                               Vertex RAS       (-56.05  0.42   62.6)
  Now, i want to know how the values between Vertex Index and Vertex RAS transformed each other.
 I need help.
 
Best wishes!
