Xiphophorus maculatus 5.0 assembly.
 The platyfish DNA for single molecule real time (SMRT) sequencing is derived from a single male (Xiphophorus maculatus, Strain - JP 163 A) from the Xiphophorus Genetic Stock Center (Dr. Ron Walter, Director), Texas State ... University, San Marcos, Texas, USA. X. maculatus Jp 163 A are line bred (i.e., brother-sister matings) and this fish is from the 114th generation if line breeding. Sequences were generated on the Pacific Biosciences Sequel instrument (V2 chemistry) to approx. 83x genome coverage based on a genome size estimate of 700 Mb. All SMRT sequences were assembled with the HGAP4 algorithm (SMRT Link v5.0.1.9585) then error corrected using the Arrow error-correction module. Additional polishing of the assembly for residual indels was done by aligning 
50x coverage of Illumina data and the Pilon algorithm. Scaffolds were generated by alignment to a Bionano map created with the same DNA source using the Irys software. Finally, all scaffolds were ordered and oriented by alignment to the genetic linkage map using Chromonomer ( 
 Of the 704 Mb assembled genome (X_maculatus-5.0), the total assembly N50 contig and scaffold lengths are 9.2Mb (n=259) and 31.5Mb (n=103), respectively.
