Hi Meiling
to go from volume points to the surface you pretty much have to search.
We speed this up internally by compiling the surface into a spatial
lookup table then only searching through the vertices that are in each
bin, but there is no easy external interface to that code (although you are
welcome to write such a thing).

hello
I have some points defined in volume (RAS coordination) and now I want to
see these locations (vertex number) on surface. I don't know how to do it.
I can see one point using tkmedit, input the coordination and save point and
then in tksurfer, go to saved point, so I can get the vertex number.
However, now i have so many subjects, and so many points defined in volume,
how can i find these vertex numbers soon?
Thanks in advance!
