Hi,
You need a talairach.xfm which is a RAS-to-"MNI-Talairach" transform, which should be present in $subject/mri/transforms (this is the 4x4 affine transform).
The following site explains the difference between "MNI" talairach and the "real" talairach space: http://www.mrc-cbu.cam.ac.uk/Imaging/Common/mnispace.shtml

Hello all,
Does any one have a matlab routine to convert given coordinates from RAS to talarach space.
If not atleas give an indication of how to do it?
