Reply To: comparison of energy

I have a related question, referring to the RosettaDock Webinar FAQ:

Is your answer the same-kind of idea, that docking program outputs *are* in fact approximations and making one of those graphs comparing affinities vs. experiments should be treated carefully? …and what did -interface mode refer to originally?
