Hi Marina
what kind of function do you mean? There is c++ code that does this in the
file mrishash.cpp, but it is a bit complicated (you have to build a spatial
lookup table at a user-specified resolution, then use it in the vertex
finding code). Alternatively if you don't have to do this a lot you can
just run through the list of vertices and find the one that is closest to
your MNI coord

External Email - Use Caution
Dear Freesurfer experts,
I would like to convert the x, y, z MNI152 coordinates into the vertex index
of the fsaverage5.
I would like to do it with a function that can give me the vertex index as
output, because I would like to use this information in a matlab script that
continues with more calculations.
Is there any function that can give me the vertex index (which corresponds
to certain coordinates) as output?
Thank you very much for your attention.
Best wishes,
Marina
