This component flags input molecules according to the Rapid Elimination of Swill (REOS) filter rules, which are listed below. The expected input is data in SMILES, SDF, Mol or RDKit molecule format. In case a molecule violates one or more of the rules listed below, the according flags and abbreviations will be returned in a collection output column. The component also allows checking for structural alerts as defined in various sources (see below). In case one or several structural alert rule sets are checked in the component's configuration window and a molecule contains such a structural alert, the first substructure from the list is highlighted in an additional output column. Note that the component only displays the first matching structural alert from the first selected rule set. Note that checking for structural alerts might take a while. In case the input molecule matches neither a rule nor any structural alert, it will be flagged with "true" in the pass column.
