Due to the increase of complexity of the molecules I am working at the moment, I am using Tinker on a Cluster. Unfortunately I am working with atom types that are not fully parameterized for mm3 (the forcefield I am testing at the moment). Does anyone know a list, manuscript or somewhere where I may find an extended list of parameters beyond the mm3(2000)? Regards, Nick
