What do you mean by "ras matlab subscripts"? Those looks like indices,
not RAS. Assuming those are indices, then that looks right.

For going from MNI to Talairach (or vice-versa) there are also the
transforms that Lancaster derived -- these are citable because they are
published.
See
http://brainmap.org/icbm2tal/
which contains links to the relevant matlab scripts.

Dear Douglas,
That's exactly the information I was looking for. This worked perfectly. Thank
you for your help!
Cheers,

Here's how to convert from surface RAS to mni305
mni305ras = X*S*inv(K)*ras
X = talairach.xfm
S = scanner vox2ras (mri_info --vox2ras orig.mgz)
K = tkreg vox2ras (mri_info --vox2ras-tkr orig.mgz)
ras = surface ras
If you want to go from mni305 to approximate talairach, you can use this

Dear FreeSurfer experts,
How does one properly convert from surfaceRAS coords, as provided by
fs_read_surf.m, to talairach coords? I have tried using freesurfer_surf2tal.m
posted on the web by Darren Weber, supplying it with transform data from
transforms/talairach.xfm, but the values returned
