[chimera-dev] Following on new atom types (again)

[Elaine Meng]

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)

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.
