The effect of the mixture parameter γ on the performance. Performance is measured by the number of true relations that are detected before the first false positive (see section for more details), (a) Exploring γ in the range [0,1] using prof _ss with true secondary structure information, (b) Magnification of the range 0–0.15. The peak is obtained at γ = 0.055. Approximately the same value is obtained when using prof _ss with PSIPRED predicted secondary structure information and also when using predicted information after the probabilities were rounded such that the most probable state is assigned the probability of 1 and the other two states are assigned probability of 0.
