WebThe SMARTS patterns for specified functional group (s) are retrieved from file, Functional_Group_Hierarchy.txt, available in RDKit data directory. The names of valid functional groups and hierarchies are dynamically retrieved from the functional groups hierarchy file and are shown below: AcidChloride, AcidChloride.Aromatic, … WebAug 3, 2024 · 193 matches Enumeration + tautomer-insensitive queries Here we will use the RDKit’s TautomerQuery class to do tautomer-insensitive substructure queries.

RDKit blog - Generalized substructure search
WebThis software finds the maximum common substructure of a set of structures and reports it as a SMARTS string. The SMARTS string depends on the desired match properties. For example, if ring atoms are only allowed to match ring atoms then an aliphatic ring carbon in the query is converted to the SMARTS " [C;R]", WebMost toolkits have have a way to find all matches for a given SMARTS and a way to find all unique matches for a given SMARTS. "Unique" here means that no two different matches will have the same set of matched atoms. The point of this task is to show how that's done.
