I am using ChemBio3D Ultra and its Autodock interface to examine the binding of a peptide ligand to a protein receptor. I successfully installed Autodock4 and Autodock tools and have them routed to C:\Program Files (x86)\The Scripps Research Institute and C:\Program Files (x86)\MGLTools 1.5.4, respectively. Using the "setup autodock calculation" feature, I prepared my receptor, ligand, GPF and DPF. When I go to the "Docking" tab on the interface and click "Run Autodock", I get the following error message: "'C:\Program' is not recognized as an internal or external command, operable program or batch file'". The accompanying prompt states, "Docking job has not been properly completed." My working directory is "C:\AutoDock_CB3D".
How can I resolve this error? Thank you in advance for your help.
