[Chimera-users] Docking problem in my Protein ligand

[Elaine Meng]

It is not possible to answer your question without any information. 

First, make sure you change the "Executable location" in the Chimera "Autodock Vina" tool to Local and enter the location of the downloaded executable on your computer, as it says in the Help page:

> <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/vina/vina.html>

That page also explains the options and what you need to do to set up the calculation.  There are lots of steps and a failure might mean that you did not do them correctly, or that no docking positions are possible in the search box that you defined.  If you think you did all the steps correctly but you get an error message, don't send it by e-mail here, but instead use Chimera menu Help... Report a Bug to send us the error message.  In that report, you should also describe completely what steps you did before getting the error message.

Or, you could try to use Autodock Vina directly (not using Chimera). See the Autodock Vina website for documentation, tutorials, etc.
