Chemistry Development Kit nodes for KNIME

About the nodes

These nodes have been developed in collaboration with the KNIME group. The nodes provide some basic chemistry functionality to deal with molecular compounds. Currently the following features are available:

• Conversion of molecules to and from SDF, Mol2, Smiles and CML
• Sketching of molecular structures
• Calculation of 2D coordinates
• Substructure search
• Visualisation of molecular structures in 3D space
• Calculation of fingerprints and Tanimoto distance
• Manipulation of explicit / implicit hydrogens
• Calculation of a range of molecular properties, XLogP and Lipinski's Rule of Five
• Structure connectivity testing

The CDK KNIME integration is under constant development. If you have any questions, bug-reports or suggestions for new nodes, please let us know in the CDK KNIME forum.

About the CDK

The Chemistry Development Kit design originated from a meeting on September 27-29 2000. Over the years, the CDK library was developed and evolved into a fully blown open source and open development chemoinformatics package with code reaching from QSAR descriptor calculations to 2D and 3D model building.
