It is very common to cluster genes based on their expression profiles, and also very common to integrate Gene Ontology to observe the distribution of biological processes, molecular functions and cellular components for a given gene list. But, what if the two in combination? The Gene Ontology distributions across a variety of gene clusters may give us a new...
