Analysis of ΔGDT values for selected GOBA measures in CASP8, CASP9-in-contest and CASP9 validation sets. The bars show in how many cases in a validation set the best selected model was within a certain GDT range from the objectively best model. Sets are labelled with A - CASP8, B - CASP9-in-contest and C – CASP9). Green denotes percentage of targets within 1 GDT, yellow [1,2), orange [2,10), black greater than 10. The yGA-family measures considerably outperform GA metrics.
