Workshop Description

Restriction site Associated DNA Sequencing (RAD-Seq) sequences short regions immediately flanking restriction sites. RAD-Seq enables cost-effective marker discovery and genotyping of hundreds of thousands of genetic markers in hundreds of samples in ANY species, with or without a reference genome. This three-day workshop will practice hands-on analysis of RAD-Seq data. We will use popular stacks pipeline ( to de novo assemble RAD loci for species lacking a reference genome.

  • RADseq Basics
  • RADseq data characteristics
  • Algorithmic details of stacks pipeline

Slides for day 1 can be found here.

  • Run the stacks pipeline from raw reads to de novo assemble RAD tag loci.
  • Apply various filters, call variants and estimate summary statistics of genetic variation.

Slides for day 2 can be found here.

  • PCA analysis to detect population structure

Slides for day 3 can be found here.
