Relative sensitivities/PPVs. A heat map showing the relative sensitivities and PPVs of the different prediction methods, or between prediction method and known structure. $\mathrm{KH}99^{\prime }$ and GG1, produce very similar structures which is not surprising, given they were found by changing one and two rules of $\mathrm{KH}99^{\prime }$ respectively. Otherwise, the methods have relative sensitivities/PPVs of approximately $0.5-0.6$, which is as expected, given they are all designed to predict RNA secondary structure. However, it is clear that they are markedly distinct from $\mathrm{KH}99^{\prime }$ in their structure predictions.
