Hisotgram comparing the Q3 (light) and SOV (dark) scores of PROTEUS (right 3 bars) versus PSIPRED, JNET, and TRANSSEC for the test set (N = 1644) of non-homologous EVA sequences. Data for YASPIN, PORTER, PROF-KING, PROFSEC, and SAM-T99 are also shown. These were calculated from a smaller (N = 30–39) subset of sequences and predictions posted on the EVA website and on the PROTEUS home page. The Q3 score is written at the top of each predictor's set of bars. Standard deviations are shown as error bars.
