Dependence of F
on the protein structural classes. The Fcar(0) (solid bar) and Fcar(8) (full bar) values were grouped and averaged over each SCOP class. For this analysis the 5 extreme superfamilies from Figure 11 were not included. The symbols a, b, c, d, and t represent all-α, all-β, α/β, α+β, "others" and all classes, respectively. The method names are given on the x-axis.
