Hi Tao,
Doug would know the answer to this. In principle yes, but it depends on the origin of the various coordinate systems. I think it's documented in excruciating detail on our wiki.

Hi Bruce:
I have a question regarding the command xfm_read. Should I use the 'talairach.xfm' under subject/mri/transforms/ as the input file? It seems that there is transformation matrix in it. Now, in tksurfer, if I click a point in the surface, I will get a "vertex RAS" xyz, and a "vertex Talairach" xyz. I assume that if I apply the transformation matrix (from xfm_read) to "vertex RAS" xyz in MATLAB, I shall get the same "vertex Talairach" xyz as in tksurfer. Am I right? Thanks!
