If you only made edits to the aseg, then you can run:
recon-all -s subject_name -autorecon2-aseg -autorecon3
which omits some stages that don't need to be redone (but which would
otherwise be included if you use the -autorecon2 flag).

If you in addition added control points, then you would run
recon-all -s subject_name -autorecon2-cp -autorecon3
which includes the stages needed to handle the aseg edits as well.
