if you have the voxel index (col, row, slice) then you can:
V2R = [ -1.00000 0.00000 0.00000 128.00000 0.00000 0.00000 1.00000 -128.00000 0.00000 -1.00000 0.00000 128.00000 0.00000 0.00000 0.00000 1.00000 ]
crs = [col row slice]';
xyz = V2R[crs+1; 1];
then find the vertex whose xyz coors are closest to xyz

Hi freesurfer experts,
I have a single subject anatomical data in freesurfer. If I know the volume index of a point on the surface of the cortex ( from T1.mgz in TkMedit), how can I find out the corresponding vertex index or the vertex RAS in TkSurfer. Thanks. BTW, I am using matlab.
Thanks,
