[Freesurfer] Subcortical segmentation

Hi, I noticed that routinely checking the subcortical segmentation (aseg.mgz) is not part of the Recommended Reconstruction Work Flow. Is this because the subcortical segmentation is highly accurate, or because manual intervention in the aseg is not recommended anyway? Thanks, Martin Ystad PhD
