Hi all,
I want to get an ascii file listing the normal vectors of each vertex of the surface (white or pial). In http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg02210.html mri_surf2surf is adviced to used but I could not find any example usage for creating vertex normals. And I appreciate any help on converting the output of the mri_surf2surf to ascii file.
One more question about the vertex normals. using tksurfer to see the surfaces, the normals of the selected vertices are printed on the console. to use mri_surf2surf the sphere.reg files are needed and they are created at the 3rd step of reconall. If there is any straightway to get those vertex normals from the surface definition like tksurfer do, I prefer it since I do not want to wait for the reconall 3.
Thanks in advance.
