  1. A large number of inconsistencies have been found, and the problems corrected. The number of inconsistencies in each evidence code group are shown here, both as an absolute number, and as a percentage of the total annotations with that code. Note that the high rate of EXP annotation flags are due to Reactome virus annotations (when this is corrected for, the EXP error rate drops to nearly zero).
