Figure 2

Three unique features used for classifications regarding halophilicity revealed by the feature selection algorithm of RF. Pairs of box-and-whisker plots are shown for each feature: positive charge, normalized frequency of beta turn, and Phe content. Box-and-whisker plots represent non-halophiles and halophiles from top to bottom. The feature values are normalized from 0 to 1 from left to right. (+) signs represent outliers.
