[Chimera-users] Problem with autodock vina in chimera

[Elaine Meng]

Hi Don,
The Autodock Vina program is not included with Chimera.  Chimera just sends the input to an outside web service (managed by a different research group, not ours) that is running Autodock Vina, and then shows the results when they are sent back. This is all described in the manual page for Chimera’s interface to this tool:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/vina/vina.html>

I am not aware of any changes relating to this interface in Chimera nor in the web service, but it is possible there was a change in the web service that we don’t know about.

Also, as mentioned below to Luana, please consider the caveat in the boxed warning in the manual page, that this web service does not allow the amount of sampling that would be needed for most research purposes.
Best,
Elaine

Tested using a recent version of Chimera.  If I show the Reply Log (open from Favorites menu) it says something like this when the calculation finishes:

Apparently, everything goes well, I even receive a message in chimera saying that I can see the results in the directory chosen. However, when I use the option "ViewDock" I can not see the results and I get I message saying that the file .pdbt does not appear to be dock out. Also, the docking calculation goes really fast, not like before that I used to take some time. In my inspection of the .pdbqt file created in the directory from the docking calculation (using note pad) it just has the compounds and the flexible bonds, it does not have the energies of the complexes ligand-protein.
