Dear Prof. I have a question about g_rdf. I have a box consists of 500 surfactants that make 10 micelle. I want to compute rdf for surfactant relative to the center of mass of micelle. When I do g_rdf, the program ask me 2 groups that the first one is COM, but it is COM of molecules that I defined in index file. If I select the surfactant molecules as the first group for COM, this means the COM of micelle or just surfactants? If it select just COM of surfactants, then what do I do for selection of COM of micelle? Please help me.
Best Regards Sara
