Workflow Chemical2URIs (1)

Thumb
This workflow will map a chemical name or identifier to uniform resource identifiers (URIs). First the ChemSpider web service is used to map the chemical name to a ChemSpider identifier, then the ChemSpider identifier is mapped to URIs via the Open PHACTS platform.

Workflow Chemical structure extractor - img2structure (1)

Thumb
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...

Workflow Chemical term extractor - text2structure (1)

Thumb
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.

Workflow RDKit-bioisosteres (1)

Thumb
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...

Workflow Download Structures from PubChem given che... (1)

Thumb
This workflow takes the input file containing chemical names and returns a single SDF file of structures. The names are searched against pubchem compounds via e-search. If the compound name is found an XML file containing PubChem ID is returned.The max return compound_ID is set to 1 which could be increased. If the compound name is not found then no ID is returned.  The pubchem compound_ID is then used to download structures from PubChem.
