Autodock and Surflex accuracy: The dock with the lowest rmsd is presented, regardless of ranking. Parts A and C present the rmsd calculated without taking into account ligand or nucleic acid symmetry, for Autodock and Surflex, respectively. Parts B and D include ligand and nucleic acid symmetry, for Autodock and Surflex, respectively. Black = daunorubicin, blue = distamycin, red = ellipticine, green = pentamidine.
