  1. The accuracy of the automatically-generated mappings is evaluated by a 20-fold cross-validation process using 31,589 sample proteins. The COG-to-GO mappings achieve moderate average precision (80.0%) and low average recall (33.0%) for GO annotation. However, the COG-to-EC mappings, evaluated in a similar cross-validation procedure, achieve excellent performance with 99.8% precision and 96.6% recall.
