It sounds like you need to make sure to specify an output location where you have permission to read and write files. For example, my directory (Mac) is /Users/meng and I can specify output as /Users/meng/test (or /Users/meng/Desktop/test , etc.) to create several files with filenames that start with “test”… but of course you would need to specify a different pathname according to however your computer is set up.

I have run this with both the web based option and the local option and get the same error "[Errno 13] Permission denied: 'trial.receptor.pdb'" I don't see a way around this error. Do I need to run the program as Administrator?

It should be reasonably friendly if you open the ligand and receptor as two separate models (from two separate input PDB files) and just fill in the required fields in Chimera’s Autodock Vina dialog, including drawing a box with the mouse in the main window to define a search area.

They might be useful for explaining what the advanced parameters mean, but you wouldn’t want to try to follow them step by step. Also keep in mind that Autodock is a different program from Autodock Vina.

I have tried several times to perform this with one of the autodock tutorials and can't get it to work under chimera.
