  1. These counts and ratios were calculated from pairwise comparisons between PASA assemblies. Cases where only a single transcript supports a variation were excluded. For each variation type, SE, IWI, TWI and RI, the prevalence of evidence indicates that it is the minor variation for the majority of cases examined. Note that the cognate isoform for SE is the retained exon (RE) and the cognate isoform for RI is the spliced intron (SI).
