>From a practical standpoint, it is more useful to extract the interacting
residues distances, and angles from the crystallographic structure, and use
that as your reference criteria for tuning parameters for redocking. 

If the goal is to run a virtual screen, then that would be the first step in
establishing a benchmark for docking and modeling novel structures. As has
been discussed, using DUD, or alternative scoring methods such as NNScore
are also useful for this process.

For aesthetic reasons, Vina doesn't use reference structures as additional
input. You could calculate the RMSDs between structures with, e.g. Vrms, or
other software (You'd need to split the output first, and convert it to SDF
or another appropriate format).

I believe ADT can do this as well, for a somewhat different definition of
"RMSD". Perhaps Ruth will comment on this.

Vina doesn't use genetic algorithms. I'm surprised how many people are
confused about this. You can control the time-vs-exhaustiveness trade-off
using the "exhaustiveness" parameter (see the FAQ and the video tutorial).
