Metabarcoding analyses (using FROGS and Phyloseq)


This course offers an introduction to metabarcoding analyses at two different levels/steps: bioinformatics with FROGS pipeline in the Galaxy environment, biostatistics with PhyloSeq R package. This includes preprocessing, clustering and OTU picking, taxonomic assignation, estimation of diversity, visualization of statistics results.

Prerequisites

Galaxy, R knowledge, Linux

Program

  • Introduction to metagenomics and metabarcoding
  • Pre-processing, Clustering, taxonomic affiliation (FROGS)
  • Handling and visualizing OTU table using (FROGSSATS and PhyloSeq R package (PhyloSeq)

Learning objectives

  • Manipulate tools available for metabarcoding analysis
  • Study sample diversity by using NGS and post-NGS analysis tools
  • Visualize diversity metrics in metabarcoding approach
