Ontologizer is a tool for the statistical analysis and visualization of high-throughput biological data using Gene Ontology. Most conveniently, it can be started via the Java Webstart facility:
Note however that the Webstart facility will no longer work by default with recent versions of the Java runtime due to increased security settings. See the Webstart section for details.
A preliminary Web version that does not rely on Webstart but uses modern Web standards can be accessed via the Web Ontologizer section.
Command line: Ontologizer.jar
GUI (without SWT): OntologizerGui.jar
