Re: [phenixbb] Exclude Waters from order_solvent=true updates

Hi Pavel, thanks a lot - that's really helpful. In the meantime, I found a workaround by semi-manually re-adding the waters in question and then refining without water update, but of course this is (much) more elegant. Thanks again and best regards, Eike -----Original Message----- From: Pavel Afonine mailto:[email protected]> Date: Monday, 13.

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.

Hello everyone,

I am refining a few structures via a bash script using constrained occupancy refinement by providing a parameter file. 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.

How can I avoid this ? That is specifically excluding a number of water molecules from being updated ?

With best regards,

Eike
