I've also just modified mri_surf2surf to extract the surface normals at
each vertex. You can get the new version from:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surf2surf
There's an example in the --help on how to run it.

sure. You can convert the surface into ascii with mris_convert or load it
directly into matlab with read_surf. The normal is then the cross product
of two of the legs of each triangle. Sorry, I don't remember the ordering
but it should be obvious if you have it wrong. The indices of the vertices
Hi,
Anywhere in the "surf" directory I can find the normal direction of each
node on the GM/WM surface? Or anyway I can calculate the normal
direction from the surface files? How about the direction between the
correspoding two points on the GM/WM surface and pial surface? Thanks.
