Dear Freesurfer experts,
My question concerns the .label files and the correspondence between the vertex
numbers (in the first column) and the R,A,S coordinates.
I have the R,A,S coordinates of voxels that I want to display on the surface.
For this purpose, I created a label file with the R,A,S coordinates (col 2,3,4)
and random vertex ID in the col 1 (since I do not know what is the vertex ID
for a given R,A,S coordinate). I displayed the content of the label file via
tksurfer. However, tksurfer reads vertex ID, not R,A,S coordinates.
I wonder whether anyone knows about a function computing the vertex ID based on
the R,A,S coordinates, or an alternative solution to represent the vertices on
the surface based on the voxel coordinates--and the registration file I assume?
Thank you very much!
Best

Thanks a lot!
