Features importance.

<p>Clustering of top-ranked features and their relative importance. The nodes sizes represent the feature importance as calculated by CRISTA. Edges transparencies represent correlation such that strongly correlated features are connected by darker edges. Yellow and blue edges represent positively and negatively correlated features respectively. Abbreviations: YY- mismatches of type pyrimidine-pyrimidine; RR–mismatches of type purine-purine; MGW–minor groove width; ‘#’ represents counts (for further explanations of the features, see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005807#pcbi.1005807.s016" target="_blank">S3 Table</a>). The graph was produced with Cytoscape [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005807#pcbi.1005807.ref055" target="_blank">55</a>] using the pairwise correlation for every pair of features and their importance scores.
