Hello FreeSurfer Developers,

I need to compute the volume of specific bilateral cortical and subcortical ROIs. 
I already ran reacon-all on all of my subjects, and I extracted volumes of the ROIs 
per hemisphere of both the cortical and subcortical brain regions (aseg and aparc).

How can I compute the merged volume of both hemispheres per each ROI?
The freesurfer version I am using: freesurfer-linux-centos7_x86_64-7.1.1-20200723-8b40551

Thank you
