Dear Freesurfers, Reading the surface segmentation paper, Dale et al 1999, it says that in freesurfer the grey/white matter boundary is detected first based on voxel intensity, and then by fitting locally a plane of list variance. Is there a way to use that data to assess how clear cut the grey/white border is? For example, to distinguish the superior temporal gyrus, which has often a very distinct GM/WM border, from the precentral gyrus, which is often more blurry? thank you in advance! roberto
