Exofish analysis on a region on arm 2L of the genome of Drosophila from two different releases of annotations, and around the same ecores. (Top) Results from release 2 of BDGP. (Bottom) Results from release 3 of BDGP. (A, D) BDGP annotations on the 5′-3′ strand. (B, E) BDGP annotations on the 3′-5′ strand. The genes are represented by boxes, with vertical lines separating exons (red) and introns (white). (C, F) Ecores (blue). In release 2 (top), five ecores (numbers 7, 8, 9, 11,12) overlap four gene models, and seven ecores (numbers 1, 2, 3, 4, 5, 6, 10) do not overlap any annotation. In release 3, a large gene model overlaps all the ecores that fall exclusively in exons except ecore number 9. This ecore is part of a gene model on the 5′-3′ strand, which is predicted inside one intron on the 5′-3′ strand.
