Molecular Replacement

Procedures for molecular replacement in crystallography include self- and cross-rotation functions, translation searches, and the newly developed generalized molecular replacement technique based on Patterson correlation ($PC$) refinement .

For further reading about $PC$-refinement, see Brünger (1990), Brünger (1991c), and Brünger et al. (1991).
