Hi, I wonder how to get masks on the cerebral white matter and the cerebral cortex. In particular, I'd like to have the masks in the space of the original input image. I noticed that in the asegm.mgz cerebral white matter and cerebral cotex are explicitly labeled, but I'm not sure if this is the final result instead of an intermediate result of less accuracy. If I should use aseg.mgz, do I need to do some transformation to go back to the original space, and how to?
Thanks, Kai
