This is not a "standard" modeling operation that Amber supports. Only
you know how you want to choose which 200 waters (out of the thousands
that are there) to replace. Once you choose the waters to replace, just
delete them from your PDB file, and replace with oxygen molecules at the
same position -- orientation probably won't matter, since they will rotate
fairly quickly as you equilibrate.
...good luck....dac
