Hi Bruce, thanks for your explanation. I was thinking the the segmentation region is used to calculate cortical thickness, by the way, is it used for calculate something? such as the GM volumes? I want to know this to be sure if in some point I have to fix this. About the heterotopias, is a good output to have someones classified as WM, other as GM and sometimes are outlined by the yellow line and sometimes are not?
