Atom-based prediction accuracies for each of the 30 protein atom types.

<p>The x-axis represents indexes for the 30 atom types shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0037706#pone-0037706-t001" target="_blank">Table 1</a>. The y-axis shows averaged two-class prediction MCCs from the 5-fold cross validation of the ANN_BAGGING and SVM_BAGGING predictors trained and tested for each of the specific protein atom type with the S432 dataset. The prediction MCCs for the independent test with ANN_BAGGING on the S142 dataset are also shown for comparison.
