Poeciliia formosa (Amazon molly) Sequence Assembly Release Notes
 The Amazon molly DNA for shotgun sequencing is derived from a adult female (Poecilia formosa; fish id Pfo_4394_1 and Pfo_4394_2) within the laboratory of Dr. Manfred Schartl at the Biocenter of ... the University of Wurzburg, Germany. Total sequence genome input coverage on the Illumina HiSeq instrument was approximately 95x (45x fragments, 45x 3kb, 5x 8kb and 0.05x 40kb), while the assembled coverage was 85x. 
 The combined sequence reads were assembled using the ALLPATHS software (Broad Institute). Two independent draft assemblies were created, both ALLPATHS with different coverage parameters, then merged with graph accordance methods (Yao et. al. 2011. Bioinformatics). The merged assembly was further improved with the external scaffolding tool SSPACE. Final steps were to align scaffolds to the platyfish chromosome reference to evaluate synteny and alignment of 3kb reads to assess mate pair discordance with REAPER. Information from both sources was used to break misassembled scaffolds when evidence was sufficient. The final draft assembly was referred to as Poeciliia formosa 5.1.2. This version has been gap filled and cleaned of contaminating contigs. The assembly is made up of a total of 3985 scaffolds with an N50 scaffold length of almost 1.6Mb (N50 contig length was 57kb). The assembly spans 714Mb. 
 This work was supported by NIH grant R24 RR032658-01 to Dr. Warren, Washington University School of Medicine.
