Better go for QM polarization docking coz DNa and RNA containing highly electron rich atom and coz of their polarity u should do QM polarization docking.
Yes. It is possible but the size of the file in case of DNA molecule should be low or else it would take ages to complete. Select DNA (a low MB file)as the macromolecule and protein as the ligand. All the best.
Selecting protein as a ligand in pdbqt format through open babel produces some error "Unknown or inappropriate tag" while docking with RNA as a receptor using autodock vina. How to convert protein from .pdb to .pdbqt without error?
