Hi Ansuman, Phenix.refine* will place metal ions if you ask it to:
- *Ion placement* extends solvent picking to build elemental ions such as calcium and zinc. To enable this option, simply enter a list of the elements to search for; this will also enable solvent picking as a first step. This option is not recommended if you have data worse than 3.0A resolution, and works best with anomalous data. https://www.phenix-online.org/documentation/reference/refine_gui.html *other refinement programs are available.
