[ccp4bb] Dock two substrates into enzyme

[Haiying Bie]

Good morning, Everyone,
  We are trying to dock two small molecule ligands into a big active site
of the enzyme.  We tried to dock two simultaneously using Autodock Vina,
but one always got kicked out.  Is there a way we can dock both ligands?
Thanks for your suggestions.
Best,
Haiying
