In the example there is a line window.cy, so I try to run that in the console. RC圓 is an R package in Bioconductor that communicates with Cytoscape via its REST API, providing access to the full feature set of Cytoscape from within the R programming environment. This is the official channel for the Cytoscape Consortium.

I try to export the graph to image using: var png64 = cy.png() ĭocument.querySelector('#png-eg').setAttribute('src', png64) )Īnd get the error Uncaught TypeError: document.querySelector(.) is null Cytoscape is an open source bioinformatics software platform for visualizing molecular interaction networks and integrating with gene expression profiles and other state data. I successfully make a HTML file containing this basic graph.
