Sorry - yes thats what I am interested in a bitstring stored in a database for every molecule that can be searched first before doing substructure searching.
Thanks >I think the idea is to have the bit strings precalculated for a set >of molecules. Then rather than doing a substructure search over all >the molecules, you can do a fast bit comparison, and get a smaller >number of molecules to perform the substructure search on. >That is the way we do it in our databases here - definitely saves time!
