Accessing the HELM Monomer Library
Accessing the HELM monomer library with KNIMEThis workflow retrieves the latest version of the HELM monomer library via the REST API for lib.monomer.org (as a JSON),and exemplifies several concepts:---> Uses the 'GET Request' node to access a JSON string containing the HELM monomoer library via the web(lib.monomer.org)---> Shows how the 'JSON path' and 'JSON to Table' nodes can be used to extract information from JSON-formatted data---> Uses 'Renderer to Image' node for conversion of chemical structure to PNG; enables views in javascript nodes freely, orwhen packaged as metanode/WebPortal views.---> Uses JavaScript tile or table views to display structures and metadata, or generated statistics from the library.---> Guided analytics: Uses CDK community nodes to enable a user-guided substructure search on the monomer library,and JS nodes for visualization of the results. Compute some basic categorization and count stats and views on the HELM monomerlibrary This particular GET request can be structured in a couple ofways: simply by 1) adding the address to the URL free field(top), or 2) by formatting the URL/URI as a column (bottom). Parse information from the JSON using the 'JSON Path' node &'JSON to Table' node Example of substructure searching using CDK nodes, and display of results using the JSTable View node Create a boolean column that captures the embedded Ionisname string from molfile, then delete the Ionis name stringfrom the molfile.
