Try using mri_label2label with the --paint option. I think the vertex
numbers need to be -1 (not random numbers). You will also need to
convert the RAS to "tkregisterRAS", one of our internal coordinate
systems. See
https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems, you'll need
to do the inverse of case #1.

/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?

Thanks a lot!
