Performance evaluation. Performance evaluation of catalytic site prediction. Lines show the performance measured by the AUC measure for subsets of the original dataset obtained by setting an upper limit on alignment size (ranging from 10 to 168 sequences in an alignment). The legend is sorted on score performance for the original dataset (equal to the right terminal values of the graph), and also shows the numerical AUC value for this case. Lines and score names are colored acccording to the clustering shown in Figure 1 as; red: cluster A, blue: cluster B, green: other scores.
