>From ${AMBERHOME}/test/tip5p/prmtop:
*%FLAG MASS*
*%FORMAT(5E16.8)*
*  1.60000000E+01  1.00800000E+00  1.00800000E+00  3.00000000E+00
3.00000000E+00*
That's for TIP5P water atoms *O   H1  H2  EP1 EP2*.  I cannot understand
this.  Not at all.  At what point were virtual sites ever assigned any
mass--they would then be atoms, and the diffusion coefficient would be way
off (not to mention the system density).
