Figure 12. Grid layout of the 2,467 gene probes of Eisen's yeast dataset.

Three biological processes are highlighted: Glycolysis, Protein Synthesis and Protein Degradation. Overall, the genes are mainly located according to their biological function, even when they were assigned to different clusters (i.e. Protein Synthesis and Protein Degradation). As expected, sometimes probes for genes that share a GO term annotation are located in different clusters, but due to the global optimization nature of QAPgrid, these clusters tend to be close together in the final layout.
