Similar to MolScribe, a frequently observed error in RxnScribe included a nitrile that was misrecognized as an isonitrile. In other cases, RxnScribe added some erroneous inert reactants, e.g. like ethane, whilst the main starting material and product were correctly recognized -in these cases we nevertheless considered this reaction as correct. The same forgiving procedure was used when in the image a polymeric resin holding a reagent/reactant was represented by a circle which was translated by RxnScibe as a methyl group.
