[i] std3 contains 222 genes and 909 exons; std1 contains 43 genes and 123 exons. The annotated exons were taken from the set presented by organizers of GASP at the time of the initial data analysis. Later corrections were not included.

[ii] (Pe) Number of predicted exons; (Ce) number of correctly predicted exons; (Cg) number of correct genes; (Pg) number of predicted genes; (Pe) number of correctly predicted genes.

[iii] (Sn) Sensitivity (%); (Sp) specificity (%). At the exon level the second number after the diagonal shows sensitivity, taking into account exactly predicted and overlapped exons.
