Autodock Vina docking with CNN scoring model rescoring

Software

docking performed with smina static binary available at https://sourceforge.net/projects/smina/files/ with default scoring function, then rescoring performed using gnina commit b3fa6ae13fc6b42924f49b2d751d68f1bc14bc08 available from https://github.com/gnina/gnina and the default CNN scoring model, conformer generation performed with rdkit via https://github.com/dkoes/rdkit-scripts/rdconf.py.

System Preparation Parameters

rdconf.py was used with the defaults except --maxconfs=1 was specified. Water was left in the receptor structure for docking.

System Preparation Method

for each SMILES input, a single conformer was generated via rdkit using the UFF force field. All compounds were docked by smina using the Autodock Vina default scoring function.

Pose Prediction Parameters

Reference ligands were used to define a box, and then 8 Angstroms of padding were added to each face of that box to define the search space for docking. The random seed was set to 0 and the exhaustiveness was set to 50. The default number of final conformers was used which is 9. To be added to the final prediction set, a pose was required to differ from poses already in the set by more than 0.5 RMSD in order to ensure pose diversity.

Pose Prediction Method

Compounds were docked using the Autodock Vina scoring function; docked poses were rescored using gnina's default CNN scoring model and then ranked by their predicted scores. The best-scoring pose was chosen, and subsequent poses were chosen in order of rank if they differed from existing poses in the chosen set by greater than 0.5 RMSD until at most 5 poses were chosen.
