[Chimera-users] AutoDock Vina

[Elaine Meng]

Hi Hernando,
The Chimera tool named “Autodock Vina” just connects to an outside web service (at a different lab, not at UCSF) that is running Autodock Vina.  Because it is a shared resource, this web service does not allow very much sampling of space, and it only allows docking one small molecule at a time.  

The dialog choices only go up to 10.  I believe if you use the “vina” command implementation (uses same web service) you can specify num_modes up to 20, but that is still relatively low compared to what is used in general practice.

To do better (more intensive) sampling of space, and/or dock a lot of small molecules in a database-search mode, we recommend downloading Autodock Vina and running it directly.  It is more work to learn how to use it directly, but then you have full control by using the config file that Ibrahim mentions, as needed for most research projects. 

Autodock Vina website:  <http://vina.scripps.edu>

The Chimera dialog and command can also be told to use a local installation, but to the best of my knowledge they are still limited to the same num_modes as mentioned above.
I hope this helps,
Elaine
