RDKit Count-Based Fingerprint

Generates hashed count-based fingerprints for an input RDKit Mol column and appends them to the table. Several fingerprint types are available. Not all settings are used for each type. Settings that are not supported by a fingerprint type will be disabled/hidden and will have no effect. The settings a fingerprint gets generated with are made available as column properties and can be visualized with the RDKit Interactive View Node.

Options

Fingerprint type

The type of fingerprint to generate. Choices are:

• Morgan: Circular fingerprint based on the Morgan algorithm and connectivity invariants (ECFP-like)
• FeatMorgan: Circular fingerprint based on the Morgan algorithm and feature invariants (FCFP-like)
• AtomPair: Atom-pair fingerprint
• Torsion: Topological-torsion fingerprint

RDKit Mol column

The column containing reactant molecules

New Column Name

Name of the fingerprint column in the output table.

Remove source column

Toggles removal of the input RDKit Mol column in the output table.

Advanced

Fingerprint Settings - Num Bits

Number of bits in the fingerprint.

Fingerprint Settings - Path length

Path length to be used (Torsion only).

Fingerprint Settings - Radius

The radius of the atomic environments considered.

Fingerprint Settings - LayerFlags

Which atomic layers should be included.

Fingerprint Settings - Min Path Length

Minimum length (in bonds) of the paths to be considered.

Fingerprint Settings - Max Path Length

Maximum length (in bonds) of the paths to be considered.

Rooted Fingerprints - Create rooted fingerprint

Check this option to create a rooted fingerprint based on an atom list. This option is not applicable to all fingerprint types.

Rooted Fingerprints - Atom list column for rooted fingerprints

The column containing the atom lists that are necessary when calculating rooted fingerprints. Instead of a list it is also possible to provide an integer column with a single atom index.

Rooted Fingerprints - Include atoms

Check this option to include the atoms when calculating rooted fingerprints or uncheck to exclude them.
