Yes, mri_segstats will do it, but you need to sample the aseg into the native space. see https://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat

I think mri_segstats includes the mean (and std) of the intensity within a structure so you could run it on the orig.mgz and norm.mgz. Doug knows more about this, but he is off at HBM, which will slow his response time.

Hi Bruce, Thanks for your reply. I appreciate your help a lot! Just a simple question. How to check the ratio of amygdala in intensity in the orig.mgz with other gray matter? I am looking forward to your suggests.

Cheers, Jiachen
