Workflow Type: Galaxy

This workflow performs variant and genotype calling on whole-genome paired-end sequencing data from organisms of any ploidy to produce annotated VCF and TSV files

  • File[]
Reference Genome fasta Reference Genome fasta Reference FASTA file to use as reference for variant calling
  • File
Set Ploidy for FreeBayes Variant Calling Set Ploidy for FreeBayes Variant Calling This step sets ploidy for FreeBayes Variant Caller
  • int
