Hi FreeSurfer list members,

I'm working on a white matter hyper-intensity study, and trying to group the segmented WM labels in lobes based on the wmparc.mgz file made by recon.

But I found that there's a large part of "unsegmented WM" near ventricles, and wonder if such labels are consistently assigned among subjects, because most of the WM hyperintensity voxels are located within these locations. Or is there other way to segment the 'unsegmented WM' in more details?

I'd appreciate any help related to this topic.
