Overview

zAMP is a Snakemake cli, written in Snaketool, for amplicon metagenomics anlysis. It includes state-of-the-art tools for performant and reproducibile analysis of 16S rRNA or ITS Illumina paired-end reads.

Starting from local fastq or SRA reads zAMP performs reads QC, ASV inference, taxonomic assignments and basic visualization plots. In addition, zAMP enables training taxonomic classifiers on specific primer-amplified regions in popular databases like greengenes2, SILVA and UNITE to increase sensitivity.

Installation

Dependencies

• Mamba
• Apptainer

from source

git clone https://github.com/metagenlab/zAMP.git
pip install -e zAMP

Usage

Prepare database

Greengenes2

• Download

wget http://ftp.microbio.me/greengenes_release/current/2022.10.backbone.full-length.fna.qza
wget http://ftp.microbio.me/greengenes_release/current/2022.10.backbone.tax.qza

• Export qza with qiime2 export

  docker run -t -i -v $(pwd):/data quay.io/qiime2/tiny:2024.5 \
  qiime tools export \
  --input-path 2022.10.backbone.full-length.fna.qza \
  --output-path greengenes2
  docker run -t -i -v $(pwd):/data quay.io/qiime2/tiny:2024.5 \
  qiime tools export \
  --input-path 2022.10.backbone.tax.qza --output-path greengenes2

• Prepare database

  zamp db --fasta greengenes2/dna-sequences.fasta \
  --taxonomy greengenes2/taxonomy.tsv --name greengenes2 \
  --fw-primer CCTACGGGNGGCWGCAG --rv-primer GACTACHVGGGTATCTAATCC \
  -o greengenes2

Run with prepared database

zamp run -i zamp/data/sra-samples.tsv \
-db greengenes2 \
--fw-primer CCTACGGGNGGCWGCAG --rv-primer GACTACHVGGGTATCTAATCC
