 Conditional entropies and entropy distances for segmentations on isochore structure, for the ground truth segmentation from [20] with k = 114. L_{
f
}: leastsquares segmentation with features f; f ∈ {gc, 2, 1, A, C, G, T} indicate frequencies of G+C, 2letter words, 1letter words, and frequency of A, C, G, or T, respectively, p_{
ℓ
}: the fraction of segmentations from ${C}_{N,k,\ell}$ with a smaller value of the conditional entropy in 10,000 randomizations; p_{
k
}: the fraction of segmentations from ${C}_{N,k}$ with a smaller value of the conditional entropy in 10,000 randomizations.
