Hi,
We evaluated CASP8 quality assessment (QA) predictors on the targets whose experimental structures were released. The QA predictors were assessed by three measures: the average correlation between predicted and true quality across the targets (i.e., mean per-target correlation), the total GDT-TS scores of top 1 ranked models, and the overall correlation between predicted and true quality of all the models (i.e., global correlation).
The preliminary results are here: http://sysbio.rnet.missouri.edu/casp8_eva/qa.php
