eDNA: Glossary

Key Points

Introduction to the bioinformatic analysis of eDNA metabarcoding data
  • Most metabarcoding pipelines include the same basic components

  • Frequency tables are key to metabarcoding analyses

Sequencing data preparation
  • First key point. Brief Answer to questions. (FIXME)

Bioinformatic analysis
  • Quality filtering on sequence length, ambiguous basecalls, and maximum error rate

  • Clustering sequences into OTUs can miss closely related species

  • Denoising sequences can create overestimate diversity when reference databases are incomplete

Taxonomy assignment
  • The main taxonomy assignment strategies are global alignments, local alignments, and machine learning approaches

  • Local curated reference databases increase taxonomic assignment accuracy

Data curation
  • The presence of artefacts inflate diversity metrics, but can be removed using novel algorithms

  • The need for rarefaction can be tested using several methods

Statistics and Graphing with R
  • A basic tutorial to conduct statistical analyses of your data
