Table 2  Prediction performance of ExAlt. Sensitivity (Sens) and Specificity (Spec) are shown for exons.

Columns are organized by exon type: Constitutive, Cassette, Multiple Splice, Intron Retention, and all exons counted together (All Exons). Row 1 shows ExAlt performance using an input exon and default parameter settings (ExAlt-Exon). Rows 2–6 show the union of different combinations of three gene finders (N-SCAN, SNAP, and Augustus) plus the input exon. (Aug. = Augustus)
