Hi Katie

I don't think anyone here knows how to do this as we don't use it. Perhaps the Brain Voyager people do?

Hrm. Ok, is there any way to view data for a subject in Freesurfer on a talairach transformed brain? What I would be hoping to do is bring up the data in native subject space, make any ROI label, then also bring the data up on a talairach transformed brain, make a ROI label, then put both labels on the same brain (either native or talairach transformed) and see if they are any different.

Also, is there a way to input a particular talairach vertex and jump to that in freesurfer, instead of just moving the mouse around and hoping to find the right spot?
