Performance on the RANK measure. For each epitope-protein pair, the rank that is assigned to the epitope when using NetCTL-1.2 is compared to the rank assigned when using the test method (EpiJen, MAPPP, MHC-pathway, or WAPP). The height of the bars indicates how often, respectively, NetCTL or the test method ranks the epitope highest. A: The HIV dataset has been used for the analysis. When comparing NetCTL-1.2 to either of the test methods, only predictions for supertypes that the test method covers are included. B: The HIVEpiJen dataset has been used for the analysis. ** The difference is significant at P < 0.01. * The difference is significant at P < 0.05.
