Four unique features used for classifications regarding thermophilicity revealed by the feature selection algorithm of RF. Triplets of box-and-whisker plots are shown for each feature: information measure for loop, Val content, Tyr content, and Chou-Fasman parameter of the coil conformation. Box-and-whisker plots represent mesophiles, mesothermophiles and thermophiles from top to bottom. The feature values are normalized from 0 to 1 from left to right. (+) signs represent outliers.
