Additional File 5:

Locations of sequences similar to Dscam exons. Locations of the sequences referenced in additional files 1, 2, 3, 4 and in the text. Locations are given on chromosomal assemblies from Ensembl version 20 or from contigs referenced in the methods. The file is in Microsoft Excel format. Stop coordinates less than start coordinates indicate that elements are in the (-) strand.
