It was more a question of: Should the -hires switch be used if you're just interested in subcortical parcellation, and your data happens to be 0.9mm, etc... or is this feature aimed at ex-vivo data or similar data.

sorry, I still don't understand. Are you really trying to generate a subcortical atlas? Or do you mean a subcortical segmentation? If the latter, then 1mm is fine. The resolution you want really depends on what you are trying to do

generating the subcortical atlas:
recon-all now produces aseg.mgz (subcortical atlas) with Hi-Res data (<1mm). The -hires flag is still necessary to include with recon-all when hi-res data is input. Changes to mri_normalize, mri_em_register and mri_watershed were made to support this feature.
