Implementation of the PAINS filters[1] using the RDKit ( nodes in KNIME (2.5.0).

Parallel processing nodes added to take advantage of mutil-core processors.

Original PAINS filters were published in SLN format. This workflow contains the SMARTS form of the filters published by the Guha group[2]. Also distributed with a 10k reference structure set from WEHI[1] which is used by default as input if no other file is chosen.

The RDKit nodes require installation of the 'community nodes' in KNIME. See http://tech.knime.org/community-installation

Based on simple sub-structure workflow by James Davidson
Modified to use SD/SMILES file as input, or manual SMILES entry, or database search.
