MoleculeRecognize[image]

recognizes a molecule in image and returns it as a Molecule object.

Details

  • MoleculeRecognize works with grayscale and color images.
  • Hydrogen atoms not explicitly included in the image are not added to the resulting molecule, but are instead treated as implicit. MoleculeModify["AddHydrogens"][mol] can be used to make them explicit for the molecule mol.
  • image should contain one or more 2D structure diagrams, returning a single Molecule object. Use ConnectedMoleculeComponents to retrieve the individual molecules.
  • Coordinates detected from the image are stored in the AtomDiagramCoordinates option in the returned expression.
  • Stereochemistry depicted by wedged and dashed bonds is automatically detected and stored in the StereochemistryElements option.
