Normalized chaos plots for apicomplexan genomes. Each pixel represents the
frequency of a given octamer sequence in the genome, relative to the frequency
expected in a randomly ordered sequence with the same base composition as the
genome in question (log scale; green <10-6; grayscale black
through white =10-6 through 5; red >5). In each plot, the
octamers [G]8, [C]8, [A]8, and
[T]8 are represented at the top left, top right, bottom
left, and bottom right corners, respectively.
