StreamableVernalis Chemistry Matched-Molecular Pairs extension for KNIME Workbench version 1.29.0.v202102191243 by Vernalis (R&D), UK
This node renders those bonds matching the indicated bond type which may form part of a valid cut pattern for the indicated number of cuts. The user can specify the number of cuts to be made (1 - 10), and whether Hydrogens should be added (1 cut only)
A variety of fragmentation options are included:
Guidelines for Custom (r)SMARTS Definition
An rSMARTS is no longer required, but may be specified if preferred for backwards compatibility. If specified must comply with the following rules. Otherwise, simply a match for two atoms separated by a single, acyclic bond must be provided
The algorithm is implemented using the RDKit toolkit
