From: COUSCOus: improved protein contact prediction using an empirical Bayes covariance estimator

MCC distributions for PSICOV benchmark proteins in case of long, medium and short range contacts predicted by PSICOV and COUSCOus. The stars represent statistical significance where ⋆ is used to represent P-value < 0.05 and ⋆⋆⋆ is used to represent P-values < 0.001
