 **nfcore/ampliseq** is a bioinformatics analysis pipeline used for 16S rRNA amplicon sequencing data.
 
-The workflow processes raw data from FastQ inputs ([FastQC](https://www.bioinformatics.babraham.ac.uk/projects/fastqc/)), trims primer sequences from the reads ([Cutadapt](https://journal.embnet.org/index.php/embnetjournal/article/view/200)), imports data into [QIIME2](https://qiime2.org/), generates amplicon sequencing variants (ASV, [DADA2](https://www.nature.com/articles/nmeth.3869)), classifies features against the [SILVA](https://www.arb-silva.de/) [v132](https://www.arb-silva.de/documentation/release-132/) database, excludes unwanted taxa, produces absolute and relative feature/taxa count tables and plots, plots alpha rarefaction curves, computes alpha and beta diversity indices and plots thereof, and finally calls differentially abundant taxa ([ANCOM](https://www.ncbi.nlm.nih.gov/pubmed/26028277)). See the [output documentation](docs/output.md) for more details of the results.

 The pipeline is built using [Nextflow](https://www.nextflow.io), a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It comes with docker / singularity containers making installation trivial and results highly reproducible.
