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.
