Doc Build Status GitHub repo size GitHub release (latest by date) GitHub issues Hits GitHub license


SimGBS.jl is registered in the General registry. It can be installed using Pkg.add,

julia> import Pkg;Pkg.add("SimGBS")

or simply

julia> ] add SimGBS


  • Reference genome of the target species in FASTA format (e.g., xxx.fasta.gz/xxx.fa.gz)

  • Flie stores a list of Illumina barcodes (e.g., GBS_Barcodes.txt)

  • (optional) Pedigree File (e.g.,small.ped)


  • GBS fragments generated by virtual digestion (e.g.,rawGBStags.txt)

  • Selected GBS fragments after fragment size-selection (e.g.,GBStags.txt)

  • Haplotypes, SNP and QTL genotypes (e.g.,hap.txt, snpGeno.txt and qtlGeno.txt)

  • File contains basic information about simulated GBS experiment (e.g.,keyFile.txt)

  • File contains simulated GBS reads in FASTQ format (e.g.,xxxxx.fastq)
