Hi Gleb, I’m not aware of any electrostatics features or plugins other than already mentioned (Coulombic, Poisson-Boltzmann). Also it is not clear exactly what kind of calculation you are looking for, but I guess we can see if any other users have ideas. Best, Elaine ----- Elaine C.

Dear Chimera users!

I am analysing several snapshots etracted from the full atomistic md simulation of protein-protein assosiation. I wounder to ask what are the Chiemra plugins might be useful to study long-rang electrostatic effect mediated initial recognition of both proteins in this system besides APBS caclucation which is more focused on short-ranged electrostatics.

Thanks for help!
