Figure 4.

SOM for 10-kb sequences of six eukaryotes. (A,B,C) Di-, tri-, and tetra-SOMs, respectively. Lattices that include sequences from more than one species are indicated in black, and those that include sequences from a single species are indicated in color as detailed in the figure above. (D,E,F) G+C% for each weight vector in di-, tri-, and tetra-SOMs, respectively. G+C% for each lattice vector is shown as described in Fig. 1, D–F. (G) Classification by the initial weight vectors for the di-SOM.
