EROS-DOCK: Coarse-grained rigid docking with exploration of 3D rotational space

EROS-DOCK is a coarse-grained docking approach that uses the physics-based ATTRACT scoring function in conjunction with a quaternion « pi-ball » representation of 3D rotational space. The pi-ball allows over 95% of candidate docking poses to be eliminated trivially due to steric clashes, thus allowing the remaining non-clashing orientations to be calculated very efficiently. In this way, the approach combines the exhaustive coverage of classical FFT-based approaches with an « exact » high quality scoring function.

EROS-DOCK was written by Maria Elisa Ruiz Echartea, with some contributions from Dave Ritchie.

Hex: FFT-based rigid docking

Hex is a very fast protein-protein and protein-ligand docking program  developed by Dave Ritchie. It uses a spherical polar correlation technique to accelerate the docking calculations. Hex can exploit highly parallel modern graphics processor units to achieve a further significant speed-up. Overall, Hex is up to three orders of magnitude faster than conventional FFT-based docking algorithms.

SAM: Assembling using symmetry

Sam is a fast FFT-based protein docking program that has been specifically designed to assemble perfectly symmetrical protein complexes with arbitrary point group symmetry.

Sam was developed by Dave Ritchie and Sergei Grudinin. The project was funded in part by the ANR (Project PEPSI), grant reference ANR-11-MONU-0006.
