Visualization of Genome Signatures of Eukaryote Genomes by Batch-Learning Self-Organizing Map with a Special Emphasis on Drosophila Genomes

Figure 2

The level of each pair of complimentary tetra- or pentanucleotides on 100 kb BLSOMs. (a) DegeTetra- and (b) DegePenta-BLSOMs were those listed in Figure 1. Diagnostic examples of phylotype separations are presented. The level of each pair of complimentary tetra- or pentanucleotides in each node on the 100 kb DegeTetra- and DegePenta-BLSOMs in Figure 1 was calculated and normalized with the level expected from the mononucleotide composition of the node. The observed/expected ratio is indicated in colors shown at the bottom of the figure.
