CDK Example (1)

• Download

This workflow reads a library from an SD file (change the default value of Read_MDL_SD_File) and identifies those structures that conform to Lipinski's Rule of Five. It then performs a substructure query, represented as SMILES (change the default value on Parse_SMILES), on the structures that pass Lipinski, and creates PNG images of those structures that contain the substructure. The image results will be found in your Taverna Data folder.

Indigo-pains-recursive (2)

• Download

*** Update 20151130 - using KNIME 3 nodes and the 'RDKit' version of PAINS queries ***The old Indigo library (1.1.13) could not take advantage of the parallelizing nodes in KNIME the way the RDKit library could. One way to speed up the PAINS workflow when using the Indigo library was to use a recursive loop that constantly shrank the list of structures being presented to the next PAINS query as structures were knocked out of the main list.Using the WEHI-10k reference set (embedded in ...

Chemical structure extractor - img2structure (1)

• Download

Extracts images of chemical structures from PDFs and converts them to usable structure data using the OSRA binaries.An in-progress (incomplete) workflow.This workflow makes use of the External Tool node to access the OSRA structure recognition binaries.So you must have a functioning installation of OSRA and it's dependencies. This may require advanced compiler knowledge on your platform, and may not be a trivial task.OSRA 1.4 is free for both the source & binary distribution. OSRA 2.0...

Chemical term extractor - text2structure (1)

• Download

This workflow demonstrates how to extract biological and chemical terms (text!) from a PDF file using the KNIME text processing nodes and attempts to convert the chemistry terms to structures.Requirements:KNIME 2.7.4KNIME Labs nodes - Text ProcessingCommunity Nodes - RDKit (to view structures)See http://tech.knime.org/communityStart by selecting the folder containing the PDF documents. Alternatively, you can use a folder with Word docs.

RDKit-bioisosteres (1)

• Download

Implementation of a simple bioisostere replacement workflow using the RDKit (2.0.0) nodes in KNIME (2.5.1). Includes short list of classical bioisostere replacements (not exhaustive), selectable by the functional group to be transformed. We added this control to the workflow as our own internal list of bioisostere replacements generated huge libraries for each structure fed into the workflow. The bioisostere replacement list is stored in a tab separated text file, so can be replaced...
