Barcodes for five prokaryotic genomes. (a) E. coli K-12; (b) E. coli O157; (c) chromosome 1 of B. pseudomallei K96243; (d) archaean P. furiosus DSM 3638; and (e) a random nucleotide sequence generated using a zero^th order Markov chain model. The x-axis for each barcode is the list of all 4-mers arranged in the alphabetical order, and the y-axis is the genome axis with each pixel representing a fragment of M bp long.
