Molecule Similarity Depiction

../../../../../_images/DepictionInitCubeIcon.svg

This cube depicts 2D molecule similarity to a reference molecule, based on 2D fingerprints.

The reference molecule is read from the init initialization port, from the field specified by the init_mol_field parameter.

The input molecules are read from the intake port, from the field specified by the in_mol_field parameter.

The type of the fingerprint on which the visualization is based on is determined by the Fingerprint Type parameter.

This cube uses “pink to yellow to dark green” linear color gradient to visualize molecular similarity. When there is 2D similarity detected between the two molecules, the color green is used to highlight the bonds and the color gets darker with increasing similarity. The color pink is used to highlight parts of the molecules that are not sharing any common fragments i.e. it represents dissimilarity.

The generated SVG image is stored in the field specified by the 2D Similarity Depiction Field parameter, and the record is sent to the success port.
