Hi Zahir,
Based on the error message, all I can suggest is to make sure that the location for output files is somewhere you have permission to write and read files.

I.e in the Autodock Vina dialog,  there is an “Output file” box.  Next to it is a button “Browse” which you should click and then navigate in the resulting dialog to set the location to some folder in which you are sure that you have permission to read and write files.

I hope this helps,

Recently in our lab we were trying to do some docking of our peptide ligands on the human Aminopeptidase N (CD13) receptor using the Autodock vina option in the Chimera. But everytime we are getting an error message and the docking stops. I am attaching the error message here. We did dockprep of the receptor and ligands. And we tried to do the docking with both pdb and mol2 files.
