mostly changing gray matter structures won't except in places like lateral putamen which can be so close to insula. The white matter in the aseg is used as the basis of the cortical intensity normalization, so if you change that substantially it will change the cortical estimates as well.

Hi

I have done the three recon-all steps of cortical segmentation in my data and I corrected manually the segmentation errors. Now, I will check the subcortical structures. The correction of this subcortical segmentation will afect the previous cortical segmentation?

Thanks
