Contribution ratios for the PC axes. Contribution ratios for the first five PC axes for segment lengths of 10–50 residues are shown here. The cumulative contribution ratio for the first three PC axes (Q₁₂₃, solid line with no symbol) and the individual contribution ratios of PC^all1 (Q₁, crosses), PC^all2 (Q₂, asterisks), PC^all3 (Q₃, squares), PC^all4 (Q₄, filled squares), and PC^all5 (Q₅, circles) are shown.
