Thank you for all of the work of the FreeSurfer team in continuing to make advances to the Freesurfer suite of tools.  I wondered if you could comment on (a) any work or plans to include hippocampal subfield, brainstem subfield, or corpus callosum subfield segmentations, and (b) the robustness of SynthSEG to defacing/refacing software as compared to Freesurfer?  Thanks very much.
