Counts N₂ (x-axis: backbone) and N₁ (y-axis: loops) for all the octamers under the M00 (left) and M1 (right) models. The color indicates the significance of the binomial test in the M00 model: blue = 'p _B > 0.01', green = 'p _B < 0.01', yellow = 'p _B < 0.001', red = 'p _B < 0.0001'. The solid black line on the left indicates the expected ratio N₁/N₂ = π₀/(1 - π₀).
