Is this what you are running?

[vertex_coords, faces] = read_surf('lh.seghead');

When I run it, it runs fine under 5.3. Is that the version you are running?

Sorry about that, here is the whole correspondance:

Hi Doug,

I used mkheadsurf function.

Hi freesurfer community,

I am trying to get faces and vertices of the head surface mesh in Matlab. freesurfer_read_surf works perfectly when I extract faces and vertices for the pial surface (from lh.pial), but I get an "unknown magic number in surface file" error when I use the same function for lh.seghead (which I assume is the head surface?).

Any help on what I am doing wrong?

Thanks!

Meryem
