Q4: For a given interaction profile, give me similar compounds.

In the Open PHACTS project, we have developed KNIME utility nodes that can be set to automatically leverage the desired content from Open PHACTS web services and simplify the construction of workflow processes.  In this workflow we use the these KNIME nodes (which can be down loaded here: https://github.com/openphacts/OPS-Knime ) with the Open PHACTS API call Compound Information followed by Compound Information (Batch) followed by Chemical Structure Search: Similarity with filter searchOptions.Threshold=0.85 followed by Compound Information to answer scientific competency question Q4: For a given interaction profile, give me similar compounds.
