Tools
PathVisio (www.pathvisio.org) is an open source pathway tool to edit,
visualize and analyse biological pathways. The visualization options are
designed to allow highly complex data visualization relevant in pathway
analysis.
Cytoscape (www.cytoscape.org) is an open source network analysis and
visualization tool. Visualization styles provide a wide variety of options to
visualize many types of different data on networks.
Challenges:
In pathways and networks:
– Visualization of
genetic variation data
phosphorylation data
methylation data
In networks:
– Hairball networks – highlight important parts in the network
– Multiple data sets in one network (e.g. time-series, multiple experiments,...)
e.g. phosphorylation sites
Visualization of data on biological networks
WikiPathways app in Cytoscape: Open a pathway as a network
Advanced Visualization Options in PathVisio
Visualize multiple datasets or time series data on pathway elements in
biological pathways. Gradient-based and rule-based visualization styles
are supported.
Flexible Visualization Styles in Cytoscape
Change node/edge color, shape, size, etc. Use edge-bundeling for large networks.
Apply continuous, discrete and/or passthrough mapping for data visualization.
