Thanks bruce, for your answer,

Does it exist a tool on FS or matlab to do such asignment of voxels from the WM-hypointensities (77) to the neighbouring labels?
If so, does it can use whoever the aseg.mgz,the aparc+aseg or the wmparc.mgz to do this asignment?

Thanks,
Gabriel

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.

cheers
Bruce
