Re: [Freesurfer] mapping the reliability of separating GM/WM

Hi Yawu

we have tools for mapping G/W contrast and CNR, but of course that presupposes that our surfaces are in the correct location (more or less). You can for example use vol2surf to sample at negative and positive proj_dist and compute this kind of thing, or I believe Doug has some binaries that do it for you

Hi Freesurfers, The contrast between GM/WM may vary regions by regions. Some regions have high contrast, some regions have low contrast, is there a method can map the reliability of separating gray and subcortical white matter?

Thanks in advance, Yawu
