Comparison of performance of RNASLOpt and PPfold(seed). Positive Predictive Value (PPV) is plotted against sensitivity. Each dot represents a single test of each method. See tables below for raw data (individual counts for RNASLOpt and PPfold(seed)).
Comparison of average Matthews Correlation Coefficients (MCCs) for RNASLOpt and PPfold(seed). The whiskers correspond to 95% confidence intervals (CIs). 'n' denotes the number of MCCs used to calculate average MCCs and CIs. See tables below for raw data (individual counts for RNASLOpt and PPfold(seed)).
