Performance comparison between GOBA and model quality assessment programs from (A) CASP8 and (B) CASP9 based on per target correlations. The boxplots show the percentiles of the correlation of particular scores with the GDT-TS per- target; whiskers - 0.05 and 0.95; box edges 0.25 and 0.75; the intersecting line - 0.5; the average values of correlation are shown by squares; minimal and maximal values are marked with crosses. Boxes with pink and red borders show the “relative” and “single model” GOBA scores respectively. The basic version of GOBA scores are denoted by empty boxes, while the striped ones show the performance of GOBA after applying the outlier exclusion procedure. Blue solid boxes are consensus methods, while red ones are single and quasi-single model methods. Gray boxes are methods which could not be classified in either of those two categories.
