Comparison of performance of Pknots and CRWrnafold. 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 Pknots and CRWrnafold).
Comparison of average Matthews Correlation Coefficients (MCCs) for Pknots and CRWrnafold. 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 Pknots and CRWrnafold).
