Figure 2. Comparison of single probe set correlations and metafeature correlations.

Figure shows plots of the correlation with MMSE score of three probe sets targeting TTN, CASK and TUG1 and three metafeatures involving these probe sets (TTN/PKRCB1, CASK/PTEN and TUG1/SCFD1). In this example, the correlations between MMSE score and the metafeatures are much better than the correlation between MMSE score and the individual probe sets.
