The following bug report has been submitted:
Platform:        Windows-10-10.0.26200
ChimeraX Version: 1.11.1 (2026-01-23 05:51:34 UTC)
Description
During Energy Minimization of this protein the Zn is removed. i have perform Addition of hydrogen then Addition of charge and then i do energy minimization in this attached protein but after the process the Zn metal is removed.

Hi Fakir,

If you just use the Minimize Structure tool, it will run Dock Prep itself and therefore remove "non-complexed" metal ions. I'm guessing your zinc doesn't have any metal-coordination bonds provided in its input file and therefore it gets removed. Since you have already added hydrogens and charges, the simplest way to get around this issue is to use the "minimize" command with the "dockPrep false" option.
I believe the other problem in your report is fixed if you use the version of Minimize Structure (or minimize command) in the current daily build.
