Speedy SMILES Clean Bonds

StreamableVernalis Speedy SMILES extension for KNIME Workbench version 1.20.1.v201906111356 by Vernalis (R&D), UK

This node cleans unecessary bonds:

  • Single bonds - only retained then they are between two aromatic atoms
  • Aromatic bonds - all removed
This is to comply with the suggestion in OpenSMILES that these bond types are implicit, and so the only need for them is for an explicit single bond between two aromatic atoms

This node was developed by Vernalis Research . For feedback and more information, please contact knime@vernalis.com
