Comparison of performance of Pknots and CentroidHomfold-LAST. 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 CentroidHomfold‑LAST).
Average Matthews Correlation Coefficients (MCC) with 95% confidence intervals (CIs) were plotted for different RNA families, for which at least 3 members were present in the benchmarking dataset. 'n' denotes the number of MCCs used to calculate the average and CI. See tables below for raw data (individual counts for Pknots and CentroidHomfold‑LAST).
Comparison of average Matthews Correlation Coefficients (MCCs) for Pknots and CentroidHomfold-LAST. 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 CentroidHomfold‑LAST).
