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
