Hi all,<div><br></div><div>How can I identify atoms like Na+, K+ in the map, from the positive density. Also can I add solvents like MPD and Tris buffer if any. Is there a specific way or do I have to run ligand fit. Is there any material I can read on this.</div>
<div><br></div><div>Thanks in advance.</div><div>Subhani</div>
