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?
sorry,

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

Hi Katie
you can view data on a tal brain by mapping the data using the
talairach.xfm transform. Since you can also use the inverse of the
transform you can map both ways. I think there is a tcl command in tksurfer
for finding the vertex that is closest to a given tal coord. Try:
select_tal
Ok, I am trying to use the select_talairach_point command, and I have it
in part of a script that uses tksurfer to load up a subject's inflated
surface, load the curvature, and load an overlay, but it doesn't seem to be
doing anything. Is there a step I am missing? What should I see if it
works
Nevermind, it turns out it was due to an permissions error.
Thanks again.

Another question. If I have a list of talairach coordinates, is there
someway to load those without having to do it individually? Or someway to
save the points after scripting to run through select_talairach_point
individually (as just redoing the command will lose the previous point each
time)?
Hi Katie
what do you want to do with them?
