Annotation Errors of Orphelia, MGA, GeneMark, and the Consensus combination. The annotation errors of the three programs: Orphelia, MGA and GeneMark and the Consensus combination in reads of lengths 100 to 700 bp. Annotation refers to the program's ability to correctly label the start and stop of the gene. 1000 fragment types were used from each of the gene types A, B, and C. For the single methods, while GeneMark accuracy annotates 300 bp and shorter reads the best, Orphelia generally annotates reads 400 bp and above the best. Taking the consensus of all the methods improves the annotation error for all read lengths.
