alvaDesc – KNIME

The alvaDesc KNIME Plugin contains three KNIME nodes:

• Descriptor: calculates molecular descriptors
• Fingerprint: calculates molecular fingerprints
• Pattern: identifies structural patterns (using SMARTS syntax)
• Molecule Reader: reads standard molecule files and can be used as a source for the other two nodes (which are also compatible with KNIME standard molecule nodes)

In order to work, the plugin requires a licensed version of alvaDesc installed on the same computer.
