Eric mentioned it, http://plato.cgl.ucsf.edu/pipermail/chimera-dev/2013/000948.html but to be more explicit, one way to change atom type is with the "setattr" command, for example: setattr a idatmType N3 sel (changes type for the currently selected atoms) Elaine On Mar 18, 2013, at 3:34 AM, Elisabeth Ortega wrote:
Dear Chimera dev. Team,
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. Probably I'm modifying the wrong files...
Then, I have other question to you regarding the IDAM Type. When I minimize, the N3 atoms become N3+. How can I change it?
Thank you so much for your time and your patience.
