MAP is developed, the Metabarcoding Analysis Pipeline, which is a sequence-to-answer workflow supporting the analysis of amplicons from highly multiplexed and replicated study designs and generates biodiversity estimates that correspond closely to a ground-truth dataset of single-specimen DNA barcode data.
Abstract
Current metabarcoding pipelines are inflexible with respect to study design and are poorly suited to long-read sequence data. To address these limitations, we developed MAP, the Metabarcoding Analysis Pipeline, which is a sequence-to-answer workflow supporting the analysis of amplicons from highly multiplexed and replicated study designs. Although MAP can analyze amplicons of any length from any genetic marker, it includes several features tailored to long-read COI metabarcoding. MAP installs from a Docker container and requires only sequence data, a parameters file, and a reference library. It produces intuitive reports, enabling users to evaluate their data immediately after analysis. We validate MAP by showing that it generates biodiversity estimates that correspond closely to a ground-truth dataset of single-specimen DNA barcode data and by demonstrating that it outperforms alternative platforms for COI metabarcoding. MAP is free, open-source, and available from: https://github.com/cbg-innov/MAP.
DNA barcode data are essential infrastructure for biodiversity science as they enable scalable species identification and integrative analyses that link sequences to specimens, taxonomy, and geography. The Barcode of Life Data System (BOLD) is a centralized bioinformatics workbench that supports the full barcode data l...

Ancient and historical DNA has the potential to resolve many open questions in biology. While pipelines for processing ancient and historical DNA exist, none combine user-friendly, configurable processing with copy number variation tracking and targeted taxonomic profiling. Therefore, we developed pastForward, a fully...

ABSTRACT Metabarcoding has become the method of choice for characterizing complex arthropod communities. The extent to which metabarcoded bulk samples will recover the same community composition as individual sequencing of all individuals in the sample remains poorly quantified. Biases such as unequal extraction of DNA...
