The short answer is : no There is no fundamental limit in the program for max torsions, or the like. However, I have not extensively tested drugs with numbers of rotatable bonds > 30. There may be some combinations of these ultra large drugs with large shallow binding sites on the surfaces of proteins that make ArgusDock choke....let me know if you find any. This is one reason I put the GADock code into ArgusLab alongside the ArgusDock engine. GADock is pretty robust and you might find it works well for some cases. The ArgusDock engine has been rung-out extensively on hundreds of test cases, but I would still classify it as a work in progress simply because it's not yet had widespread use from the general community.
