Hi Hiroyuki
by default we don't save the surface normals but compute them on the fly.
You can however use mris_convert -n to
compute and output the surface normals in an ascii format that should be
pretty easy to read into matlab.

Dear Sir,
Can the surface normals be loaded in matlab?
Is there a code for that and what variable should I look at in surf dir?
Thank you.

Hi Michael
the ascii file is first:
vertex_nx vertex_ny vertex_nz ripflag (usually 0)
.
.
.
up to # of vertices. Then, for each face:
vertex_0 vertex_1 vertex_2 ripflag
cheers

Hi Bruce et al.
I have a quick question about the interpretation of surface normal
files and the various ways you can create them with Freesurfer.
As far as I know, there are two ways to get the normals information:
mris_convert -n lh.inflated lh.inflated.normals2
and
mri_surf2surf --s fsavera
