cytoscape2png

Command line tool for converting Cytograph json graph files to png images with an optional Cytograph style json file which is applied to all of the graphs.

Usage

To install, use npm install Ringenberg/cytoscape2png. This should make ./node_modules/.bin/cytoscape2png available, otherwise use ./node_modules/cytoscape2png/index.js in its place.

Please note that all of the .json files passed to this script need to be well formed JSON.

To generate a single image from a fully specified JSON file:

$ cytoscape2png path/to/graph.json

To generate all of the images for all of the specified graphs:

$ cytoscape2png path/to/images/graph*.json

will produce the corresponding images for each graph with the ".json" extention replaced by ".png"

To generate images with a common style:

$ cytoscape2png --style graph_style.json graph*.json

will generate all of the given graphs using the provided JSON style file as specified in http://js.cytoscape.org/#style - Plain JSON format.
