Re: [phenixbb] Automated Mg & K ions picking

Hi Hasan, yes, we plan to extend water picking procedure so it can identify single-atom ions, but no specific tool is available to use right now. You need to inspect waters (for example, a water with "too small" refined B-factor is likely to be a metal), and density peaks (phenix.refine may not place a water into a density peak if it is too different from what is expected for water).

Hi, I have a low resolution data and I am trying to place Mg++ and K+ ions. As far as I know for ligand search at least 3 atoms required. Is it possible to do an automated search of these single atom ions by using phenix similar to automated water picking protocol?

Thanks.
