Homology docking benchmark provides means to generate large, customized ensembles of potential template structures from the protein data bank pdb, for the components of target complexes representing heterocomplexes of single domain proteins from the docking benchmark v4. That is, write the homology in this degree as a direct sum of a free module and a torsion module. Homology modeling, also known as comparative modeling of protein is the technique which allows to construct an unknown atomicresolution model of the target protein from. The purpose of this introductory chapter is to introduce these concepts. Analogous to group representations, group cohomology looks at the group actions of a group g in an associated gmodule m to elucidate the properties of the group.
