I see that GROMACS has an option to estimate protein volume as a function of time, but I need to know how the individual dimensions change as a function of time.

gmx traj extracts coordinates, from which you can find maximum and minimum 
values along any axis.  The output is a bit unwieldy but easily parsed.
