Hi Katie
you might be able to create a label file with the tal coords, then use mri_label2label to map it from tal to the individual subject, then load it in tksurfer which will map it to the surface. It will probably look spotty though.

I'm still trying to figure out a way to display an ROI made elsewhere on my freesurfer data. I can get all ROI I need in freesurfer in talairach points (ie. a list of talairach points that cover the entirety of the ROI space), but as far as I can see, I can only load one talairach point at a time (using select_talairach_point), and then the last point is lost with each subsequent call. What I really want to do is select a region on the surface that covers a set of talairach coordinates (instead of say, dilating from 1 talairach point). Is there any way to do this? Should I use something like the talairach transform file to change it into surface coordinates and load those like a label somehow, or is there some other way?
