Tests COVID-19 sequence analysis on Illumina Amplicon PE data
This workflow implements an iVar based analysis similar to the one in ncov2019-artic-nf, covid-19-signal and the Thiagen Titan workflow. These workflows (written in Nextflow, Snakemake and WDL) are widely in use in COG UK, CanCOGeN and some US state public health laboratories.
This workflow is also the subject of a Galaxy Training Network tutorial (currently a Work in Progress).
It differs from this workflow in
that it does not use lofreq and is aimed at rapid analysis of majority variants and lineage/clade assignment with pangolin and nextclade.
TODO:
- Add support for QC using negative and positive controls
- Integrate with phylogeny tools including IQTree and UShER (and possibly more).
