Hi

Am having a bit of a problem that may be easy to resolve.

I want to view an LGI two-group comparison I did in mri glm-fit with freeview. Each time I load the overlay (cache.th13.abs.sig.cluster.mgh). The grayscale inflated surface turns red like what is in picture-1

Please have anyone an idea why this is happening and what I can do to change it back to grayscale like picture 2
