Summary:Considerations for the use of limited-environment screens for screening generic chemical structures are discussed. The general strategy and detailed procedures for the automatic generation of screens from the extended connection table representation (ECTR) of generic chemical structures are described. A bitscreen record for generic data base structures and specific, generic, and substructure queries is described, and a number of screening algorithms are proposed.
