the _are_ read in. you may not see them, as there only are the oxyens
and thus they are only small points instead of lines. the molecule
file readers in VMD have _no_ clue of the chemistry, and thus do
not discriminate between atoms.

create a selection for those waters and show them with a
different representation (cpk, vdw) and you should see them.
