Hi Marwan,
Thanks for the interest in ODDT, I hope you found it useful. As for now the only stable empirical scoring function is Autodock Vina. We have a plan to finish the Xscore one (at least one of its variants), but it has low priority, as there is little advantage to the current implementation. We might provide a wrapper to the binaries of other SFs which are usually easier to code, but still have little added value. If you have time or students willing to implement these features, then I'd strongly recommend it.
Best wishes,
Maciek
