Hi all, sorry for my ignorance in anatomy, but I'm an engineer, not a physician. I would know what is the relationship in freesurfer between the gray matter and the cortical ribbon. I load in a matlab environment the ribbon.mgz file, and I see that this surrounds the white matter defined by the filled.mgz file; so I 'm thinking to use the ribbon file to find the gray matter voxels. Is there a way to build a file like the ribbon.mgz or the filled.mgz also for the gray matter, in which gray-matter points are highlighted like for the white matter points?
Regards
