Figure 4From: Coverage statistics for sequence census methodsComparison of the Poisson process and Markov approximation in terms of tree height. Histograms of the densities for tree height are shown for trees built from a simulated Poisson process (solid yellow) and Galton-Watson trees from the Markov approximation (blue striped) for the case of fixed fragment lengths. Each tree corresponds to one lattice path excursion away from 0 (also referred to as sequence islands or contigs). The simulations include average height θ = 6 with 14,466 trees simulated for each type (A), θ = 9 with 3,551 trees simulated for each type (B), θ = 12 with 1,429 trees simulated for each type (C), and θ = 15 with 217 trees simulated for each type (D).Back to article page
