Introduction

nf-core/vipr is a bioinformatics best-practice analysis pipeline for assembly and intrahost / low-frequency variant calling for viral samples.

The pipeline is built using Nextflow, 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.

Credits

This pipeline was originally developed by Andreas Wilm (andreas-wilm) at Genome Institute of Singapore. It started out as an ecosystem around LoFreq and went through a couple of iterations. The current version had three predecessors ViPR 1, ViPR 2 and ViPR 3
