Hi Eike,

in recent versions of Phenix you should be able to use 
ordered_solvent.keep_existing parameter. By default it is set to False 
meaning all input water is subject to inspection by the program and can 
potentially be removed. Setting it True will keep input water no matter 
what.

I am trying to model the occupancy of a ligand and the water molecules in its vicinity. This works generally well, but as soon as I switch on ordered_solvent=true, these water molecules are also filtered / updated and eventually removed.
