.right,i was wrong.I mean the parameter file.I was wondering how could i gather information from a specific AllAtom-Sim & add new lines in rbcg-2007.par file for the parameterization.Thank u.

Correct me if i am wrong, but i think when you say topology you actually mean the forcefield parameters.
Sure you can. You can obtain a probability distribution from an all atom simulation for any feature of a set of degrees of freedom. Then using the relationship p(x) = exp (-V(x)/kT), where V(x) is the potential you can obtain new ad hoc parameters.

take a look at the nanodisc papers where the parameters set that comes with VMD where obtained.

 Hello.If i am not wrong, u can add new information to your topology file using paratool on vmd and QuantumMechanical simulatios as a base.Is there a way to add new information to my CG topology file using all-atom simulations as a base?(i use the RBCG method)
thank u,Dota.
