- Revised event hierarchy panel to provide interactivity and access to the entire listing of all the Reactome pathways.
- Improved flexibility and performance of our pathway browser with a new pathway diagram visualization tool using HTML5 Canvas.
- Extended data overlaying technologies to support molecular interaction data from the PSIQUIC registry, including BindingDB, DrugBank, and GeneMANIA.
- New pathway diagram tools to search within the displayed pathway, overlay the pathway with functional interactors, and download the diagram as a snapshot or PNG file.
- Enhanced “Details” panel providing alternative displays of graphical and textual information, such as 3D structural data and citations for proteins from PDB, for small molecules from ChEBI, for the stoichiometry of metabolic reactions from Rhea, and for expression data from Gene Expression Atlas.
- Merged pathway identifier mapping, over-representation, and expression analysis tools into a tabbed data analysis portal with integrated visualization for improved pathway diagram colorization with user-supplied experimental data.
- Updated Reactome Functional Interaction plugin supports Cytoscape v3.x., providing useful tools for the discovery of network patterns related to cancer and other types of disease.
