External Email - Use Caution Hi Bruce, Thanks for the info. Can the tool display the vertexes with low G/W contrast? I would like to use those vertexes as a guide for visual evaluation. Cheers, Yawu Bruce Fischl 于 2019年12月19日周四 16:52写道: > Hi Yawu > > we have tools for mapping G/

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 binarie

2019-12-19 Thread Liu Y
External Email - Use Caution 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
