Hi. I've been having trouble showing TT Atlas Regions. The dataset I'm using, head+tlrc, is one I've converted to talairach and been able to use options like "talairach to" on. I have the "See TT Atlas Regions" button turned on, and in "-Atlas Colors" I've set the Hippocampus to blue and hit "DONE." However, nothing actually changes color when I do this. I've also tried a couple other things like toggling "see overlay," closing and reopening the images, and doing the steps in different orders, but no luck so far. Is there something else I need to do to make the colors show up? Thank you.
