The increasing availability of structurally aligned protein families has made it possible to use statistical methods to discover regions of interpositional dependenciesof residue identity. Such dependencies amongst residues often have structural or functional implications, and their discovery can supply valuable constraints that assist in the refinement of measured, or predicted molecular structure assignments.
