Dm = Drosophila melanogaster; Dse = Drosophila sechellia Rob3c; Dy = Drosophila yakuba Tai18E2; Der = Drosophila erecta TSC#14021-0224.01; Da = Drosophila ananassae TSC#14024-0371.13; Dp = Drosophila pseudoobscura MV2-25; Drp = Drosophila persimilis MSH-3; Dw = Drosophila willistoni TSC#14030-0811.24;

Dmo = Drosophila mojavensis TSC#15081-1352.22; Dv = Drosophila virilis TSC#15010-1051.87; Dg = Drosophila grimshawi TSC#15287-2541.00.

^a Genomes are fragmented and contain gaps in the Dscam genes.

^b The first number corresponds to a search with standard parameters, the second to searches with one round of recursion.

^c One of the exons is a pseudo-exon because it misses the last forth of the exon because of an in-frame stop codon.
