Hi, I have a structure with a metal beautifully coordinated by 3 water molecules. However, every time I run phenix.refine water picking they get removed (probably due to combination of being too close to metal/too deep in the density). So far I've been manually reentering them into pdb but it becomes a bit frustrating. Is there a way to fix those waters during water picking?
