Thank you Bruce,
Yes, this is what I did.
Because the insular contacts are not in the insula anymore after I use the
vertex to find the RAS coordinates for the inflated surface, my conclusion
is that this only works with surface electrodes, not depth
See this page to figure out how to get the scanner coords

Hi Giulia
find the vertex index of the vertex you are interested in, then read the
surface whose RAS coordinates you want (e.g. the white or pial) and
lookup the RAS coords of the vertex at that index.

Dear FreeSurfer experts,
How can you obtain RAS coordinates for an inflated surface when you have
vertex #?
I am using the function read_surf('lh.inflated') to find the coordinates of
some electrode contacts located in the left insula. However, when
