Classification of intron assemblies. We classified the intron assemblies that were novel with respect to a reference set according to their position relative to the other set against which we do the comparison. A novel IA can (a) fall between the genomic extent of two predictions (intergenic), (b1) bridge across two predictions (bridge), (c1) overlap the 5' or the 3' end of one prediction (external), and (d1) fall within one or more introns of another prediction (intronic). Additionally, novel IAs are labelled as complete when they are a complete ATG-to-STOP prediction: (b2), (c2) and (d2).
