We use the modules to obtain a global characterization of different conditions by a combination of activated and deactivated modules. Based on information provided in the respective studies, we annotated all arrays with 283 biological and clinical conditions that we compiled from the data published in the various studies. These annotations include tissue and tumor type, diagnostic and prognostic information, and molecular markers. For each module and each condition, we tested whether the module is induced (repressed) in a significant fraction of the arrays labeled with the condition.
