Status: R Hi, I'd like to do some conformational search of proteins, and I need a program which can calculate the energy given the interaction potential function, AND can be driven by a search program. The representation of the protein structure within the program could be as simple as the fixed bond length and angle model in ECEPP, and the potential could also be quite standard. The main feature I need is the convenience in interfacing this energy-calculation program to the main searching program. The other desirable features are: . In public domain; . Widely used, so that comparison can be made. I would appreciate you could give me some recommendations via E-mail. BTW, I have the 1975 QCEP version of ECEPP, but it's Fortran IV. Are there newer versions available in public demain? Regards, Luo Ning
