Hi Amirhossein
which structures do you mean? Like the ventricles? We usually mask those regions out using the ?h.cortex.label. The surfaces should be "frozen" in those regions in any case, meaning that the white and pial are in the same location (and the thickness is 0)

Dear All, I wonder if you have experienced or there is any report on cortical segmentation reliability in the mid-line structures of the brain, so one should take them into consideration in running group differences with Qdec?
