then I would either use TRACULA (if you have DWI) or the wmparc to generate
ROIs. I meant that you could count whether there are more lh or rh wm
labels neighboring each one to figure out which hemi they are in

Yes I did loo at the total WH-hypointensities(77), and substract them without a
problem.
What do you mean with lateralize them based on neighboring labels? How can I
perform such thing on FS?
Actually I'm interested in knowing to wich specific label o region they are.
Bests,

Hi Gabriel
we don't lateralize them by default, so look for WM_hypointensities (77)
instead. It would be pretty easy to
lateralize them based on neighboring labels.
