Dear all

I am interested doing some visualization of my cortical FreeSurfer results in other software.

In order to do so I need to some information about how the cortical surface is defined. Usually these surfaces consists of a set of 3D coordinates which gives the position of the vertices (163842 in the case of fsaverage), and a set of triangle definitions which are 3 indices into the vertex data (see http://en.wikipedia.org/wiki/Triangle_mesh )

Is it possible for me to access the triangle and vertex information of the cortical surface of the fsaverage subject?
