The "Vertex RAS" is a FS internal coordinate system "Vertex MNI Talairach" is the MNI305 coords "Vertex Talairach" is an estimate of talairach coords based on a transform from Matthew Brett see http://imaging.mrc-cbu.cam.ac.uk/imaging/MniTalairach

Hi all,

I find myself getting quite confused about different coordinates systems. Is the following correct (when viewing in TkSurfer):

RAS=MNI Talairach=MNI305 (they are all the same?) Talairach= (non linear) conversion from MNI305

Thanks,

Anita
