Background: A total of 20 female individual DNA isolates were provided as a pool in TE buffer for tsetse fly Glossina austeni courtesy of Dr. Serap Aksoy, Yale University. The sequencing plan followed the recommendations provided in the ALLPATHS-LG ... assembler manual. This model requires 45x sequence coverage each of fragments (overlapping paired reads approx. 180bp length) and 3kb paired end (PE) reads as well as 5x coverage of 8kb PE reads. For fragments and all jumping libraries (3 and 8kb) we used a DNA sample pooled from 20 female individuals. Various assembly metrics are summarized below. Total assembled sequence coverage of Illumina instrument reads was 62X (overlapping reads 42x, 2.0kb PE 13x, 4.0kb PE 7x) using a genome size estimate of 400Mb using the ALLPATHS-LG software (Broad Institute). This first draft assembly was referred to as G. austeni 1.0. In the G. austeni 1.0 assembly small scaffold gaps were closed with Illumina read mapping and local assembly. Contaminating contigs, trimmed vector in the form of X's and ambiguous bases as N's in the sequence were removed. NCBI requires that all contigs 200bp and smaller be removed. Removing these contigs was the final step in preparation for submitting the 1.0.3 assembly. The G. austeni 1.0.3 assembly is made up of a total of 2205 scaffolds with an N50 scaffold length of over 798kb (N50 contig length was 46kb). The total contigs assembly spans 358Mb.
