Dear all<br><br>I am interested doing some visualization of my cortical FreeSurfer results in other software.<br><br>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 <a href="http://en.wikipedia.org/wiki/Triangle_mesh">http://en.wikipedia.org/wiki/Triangle_mesh</a> )<br>
<br>Is it possible for me to access the triangle and vertex information of the cortical surface of the fsaverage subject?<br><br clear="all">---<br>Sincerely<br>
