Start Cytoscape and go to the App Manager (Apps → App Manager).
Click the Install from File... button and select the RINalyzer.jar file.
Repeat the same action with the structureViz.jar file.
To check if the installation was successful, go to Apps to find the RINalyzer and structureViz menu options.
Launch UCSF Chimera from within Cytoscape:
Start Cytoscape
If not using the default Chimera installation directory, set the path to the Chimera executable file in Apps → structureViz → Settings .... These settings are specific to each network in Cytoscape.
Go to Apps → structureViz → Launch Chimera.
Once Chimera has been started successfully, the last used path is saved in the session file. If no other path is specified in the structureViz Settings, this path is used for launching Chimera next time.
