if you upload a dataset we'll take a look. I am surprised to hear that you are having problems. Can you post an example image?

When I run these images the program finishes without error however the output in tksurfer is grossly incorrect. Is there a way to adjust the parameters for reading white and gray matter by freesurfer (because BRAVO has a different contrast, not as defined) so that regions and boundaries are parceled correctly?
