RADseq Data Analysis Through STACKS on Galaxy

Slidesdoi: 10.7490/f1000research.1112912.1

1 data allow scientists to gather genome wide information with a low-cost approach compared to complete genome sequencing. In this training session, we will show how to analyze RADseq data to

  1. build genetic maps2,
  2. calculate population genomics statistics3,4 and
  3. assemble paired-end loci with or without reference genome using Stacks5 on Galaxy

Stacks works with restriction-enzyme based data, including GBS, CRoPS, and single and double digest RAD. Stacksidentifies loci in a set of individuals, either de novo or aligned to a reference genome (including gapped alignments), and then genotypes each locus. See the Stacks Manual for full details. 

 has been integrated into Galaxy and is available via the GUGGO Tool Shed.


  • A general knowledge of Galaxy (for example, you should be familiar with the material in Galaxy 101 or have attended Introduction to Galaxy).
  • A wi-fi enabled laptop with a modern web browser.  Google Chrome, Firefox and Safari will work best.

Yvan Le Bras

Research engineer, INRIA / EnginesOn
Initially a marine Biologist, focusing on Populations structure, Yvan received a PhD on quantitative genetics and genomics in Rennes University. After a one year postdoc at INSERM dedicated to Integrative genomics, he investigated an e-Science approach for Life Sciences during a 3 year postdoc project at INRIA / IRISA Rennes. One of the outcome of this project, called e-Biogenouest, is an innovative Virtual Research Environment (VRE) based on... Read More →
