χ 1 versus χ 2 histogram for isoleucine: The two-dimensional histogram of χ1 (x-axis) against χ2 (y-axis) illustrates the association between the two angles. Their univariate, marginal distributions are shown as well, attached to the respective axes. The histogram marked "Training" represents the training set, while the histogram marked "BASILISK" represents BASILISK samples.
