Detailed Description

Computation of clusters of docking poses.

Pose Clustering

This class computes clusters of docking poses given as a conformation set using a complete linkage algorithm.

The class assumes the following setup

a pairwise rigid protein-protein docking
all receptor-ligand poses have already been mapped onto each other such that the "receptors" are kept fixed
the given pose set only contains the "ligands"

We offer several algorithms via the option CLUSTER_METHOD:

TRIVIAL_COMPLETE_LINKAGE: a naive implementation, that guarantees an optimal final partition.
CLINK_DEFAYS as described in D. Defays: An efficient algorithm for a complete link method. The Computer Journal. 20, 4, British Computer Society, 1977, p. 364-366. Please note that this implementation does not guarantee to find the best final clustering!
NEAREST_NEIGHBOR_CHAIN_WARD as described in Murtagh, Fionn (1983): "A survey of recent advances in hierarchical clustering algorithms", The Computer Journal 26 (4): 354–359
Note that this algorithm computes a full clustering.
SLINK_SIBSON as described in R. Sibson: SLINK: an optimally efficient algorithm for the single-link cluster method. The Computer Journal. 16, 1, British Computer Society, 1973, p. 30-34

The scope of the scoring (the atoms to be considered) can be defined via the option RMSD_LEVEL_OF_DETAIL. If the option is set to PROPERTY_BASED_ATOM_BIJECTION, arbitrary sets of atoms, e.g. binding pockets, can be used by assigning property named "ATOMBIJECTION_RMSD_SELECTION" to the respective atoms in the reference system. See also BALL::Expression.

The minimal rmsd or ward distance between the final clusters can be defined via option DISTANCE_THRESHOLD. In order to relate RMSD and ward distance, we use sqrt(ward_dist / number_of_selected_atoms) for threshold extraction.

The nearest neighbor chain ward clustering in principle computes a full clustering. Option DISTANCE_THRESHOLD gives a ward distance that is automatically used to extract clusters. Further extractions with different thresholds are possible.

The complete linkage algorithms guarantee a minimal cluster distance (max RMSD between all pairs of two clusters), specified with option DISTANCE_THRESHOLD.

The initial poses can be given as ConformationSet or as transformation file, i.e. translation and rotation of each pose. Depending on this choice, the option RMSD_TYPE has to be set to SNAPSHOT_RMSD or RIGID_RMSD. If RMSD_TYPE is set to CENTER_OF_MASS_DISTANCE, the option RMSD_LEVEL_OF_DETAIL will be ignored.

By setting the option RUN_PARALLEL to true, the user can request parallel execution. This will be performed if the execution environment is enabled (BALL_HAS_TBB), and if the algorithm supports it.

◆ refineClustering()

bool BALL::PoseClustering::refineClustering ( Options const & refined_options )

Refine a given clustering. This function can be used to refine a precomputed clustering further. An important use case would be to pre-cluster using an efficient rmsd implementation (e.g., center of mass or rigid rmsd), and then refine the resulting clusters with the general (i.e., snapshot based) rmsd.

NOTE: This function requires that clusters have already been computed. In the case of a full hierarchical clustering, extractClustersForThreshold or extractNBestClusters must have been called previously.

Parameters

refined_options The parameters for the refinment step.
