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.
Pipeline Steps
| Step | Main program/s | 
|---|---|
| Trimming, combining of read-pairs per sample and QC | Skewer, FastQC | 
| Decontamination | decont | 
| Metagenomics classification / Sample purity | Kraken | 
| Assembly to contigs | BBtools’ Tadpole | 
| Assembly polishing | ViPR Tools | 
| Mapping to assembly | BWA, LoFreq | 
| Low frequency variant calling | LoFreq | 
| Coverage and variant AF plots (two processes) | Bedtools, ViPR Tools |

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.
