Figure 2

Groups of phyletic patterns and COGs revealed by hierarchical clustering of patterns in species space. The presentation is similar to Figure 1, but the black and white squares are vertically compressed in order to show all 4,589 COGs in one figure. The full tree of COGs is shown at the left; at 170 COGs per 1 mm height, it is not particularly suitable for visual consumption, but some closely linked clusters (short branches) can be discerned.
