  • The extension will generate PRMTOP and INPRCD files for your system, compatible with Amber & OMMProtocol/OpenMM.
  • Multiple atom sites allowed seamlessly.
  • If this extension is installed, a reversible, subtle modification to UCSF Chimera’s MetalGeom extension will allow arbitrary elements to be placed at vacant positions, instead of just oxygens.
