<div dir="ltr"><div>Dear Chimera dev. Team,<br><br><br></div><div>I'm trying to do the same as JD. The message that I receive is when I try to minimize is "Element Pt (atom #0.1.A@PT1) is not currently supported". As Mr Pettersen told me before, I defined the parameters of PT in heme-iron.frcmod file in ../bin/amber/dat/leap/parms and I also defined the "pt" atom in the MMTK Database. Then I added the charges without the covalent bond between the PT and its neighbours and finally I try to minimize with and without the bonds. Nothing happens.<br>
Probably I'm modifying the wrong files... <br><br></div><div>Then, I have other question to you regarding the IDAM Type. When I minimize, the N3 atoms become N3+. How can I change it?<br><br><br></div><div>Thank you so much for your time and your patience. <br>
