Hi Linn
it looks like a hypo intense region surrounded by a hyper-intense one, no? I think if you edit those voxels in the aseg.mgz to be "white matter hypointensities" or "lesion" then run the recon from there forward it should be ok Bruce

Hi again, Sorry for being unclear. Here is a picture of the lesion. If I understand correctly it is now NOT included as white matter. All I want to do is include it as white matter, so that it will be registered as a hypo-intense area in aseg.stats. So the way to do this is to edit the aseg.mgz and not the wm.mgz? Cheers Linn Norbom

Is it possible to include these areas in white matter and additionally keep the statistic volume of these areas as hypo-intense-wm in the aseg.stats?
