No clue. Even if you had a principled clue based on the cubed root of the volume difference, there is such variability in size that it's probably not as effective as just trial and error (300, 600, etc.). > Should I, e.g. tell caret it's a rodent? Caret isn't that smart. It uses the species very sparingly -- probably just to turn off some ventricle footwork in the inner or outer boundary routine. > > Freesurfer might not be so hard for marmoset compared to macaque, since > there's no gyration.
