All of the volumes, except the inner and outer boundaries, are segmentations, 
rather than structural volumes (as far as I know).

But you could find one of those intermediate volumes -- possibly named like 
hindbrain* -- and subtract that volume from the anatomical volume, and then use 
the volume math features to set the floor to 0.  There are lots of 
caret_command tools for this sort of thing, not to mention FSL/AFNI tools 
(e.g., 3dcalc).

I'm surprised Caret gets rid of the marmoset hindbrain at any resolution -- 
cool.
