TP interaction pair normalization with respect to organism source composition. This figure shows the total number of interaction pairs in the test set (840) for each corresponding organism source combination with respect to the percentage agreement between different participating systems in case of correct (true positive [TP]) predictions. Interaction pairs of proteins form different organisms (for example, between mouse and human proteins) are basically experimental in vitro interactions.
