Dear Ching Song,
I didn't know the answer, so I just tried it, and it worked fine in Chimera 1.8.  

I opened 2vfs and deleted everything except the protein and FAD  (deleted solvent, ions, and XYL).  So that's the receptor, #0.

Then I opened some other small molecule structure to use as ligand, #1.

Then I started Autodock Vina, created the search box, entered name for output, and chose receptor #0 and ligand #1.  Looked in the "Receptor options" to make sure that "Ignore all non-standard residues" was "false".  Clicked Apply, and the job ran successfully.

I had a problem in Chimera 1.9, which I will report as a bug, but if you stick with Chimera 1.8 it apparently works.
Best,
Elaine

We would like to know if we could dock a sugar into the substrate binding site with the FAD molecule in situ.  Thank you for your help.
