you can turn this off with the -nowmsa flag I believe in recon-all. The
labels are for damaged white matter and damaged gray matter, which can be
tough to distinguish based only a T1. We have some (not-yet-distributed)
tools that do pretty well on this if you have other contrasts like
T2/FLAIR/PD.

Greetings,
I am wondering if there is some information regarding the meaning of
“wm-hypointensities” and “non-WM-hypointensities” variables from the
aseg.stats file, ie, what features are included in these variables and how
FS computes them.
I checked previous posts that have the same issue I have now.
I find some non-zero, (some cases have “quite big”) WM-hypointensities
values for healthy young brains. I find it odd.
I would appreciate some additional information about these issues.
Thank you!
Best regards,
