Hi Ali
We keep track of the vertex index of the flat maps, so you should just be able to use it to look up the coordinate of whatever other (white, pial) surface you want, then see what volumetric coordinates it is at

External Email - Use Caution Hi all,
I have been able to create my flat map in freesurfer and then do calculations using it to find a point. I then want to map that point back into the 3D space maintaining the coordinates. I was wondering if anyone had done something similar before and had any ideas. I am using MATLAB for the calculations and transformations.
