Conditional entropies and entropy distances for segmentations on isochore structure, for the ground truth segmentation from [20] with k = 114. Lf: least-squares segmentation with features f; f ∈ {gc, 2, 1, A, C, G, T} indicate frequencies of G+C, 2-letter words, 1-letter words, and frequency of A, C, G, or T, respectively, p: the fraction of segmentations from <a onClick="popup('http://www.biomedcentral.com/1471-2105/8/171/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2105/8/171/mathml/M2">View MathML</a> with a smaller value of the conditional entropy in 10,000 randomizations; pk: the fraction of segmentations from <a onClick="popup('http://www.biomedcentral.com/1471-2105/8/171/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2105/8/171/mathml/M1">View MathML</a> with a smaller value of the conditional entropy in 10,000 randomizations.
