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.

            So what resolution would make sense to use? the

            would 0.9mm isovol really cut it?
