COVID-19: consensus construction

This workflow aims at generating reliable consensus sequences from variant calls according to transparent criteria that capture at least some of the complexity of variant calling.

It takes a collection of VCFs and a collection of the corresponding aligned reads (for the purpose of calculating genome-wide coverage) such as produced by any of the four variant calling workflows in https://github.com/galaxyproject/iwc/tree/main/workflows/sars-cov-2-variant-calling ...

Parallel Accession Download

Downloads fastq files for sequencing run accessions provided in a text file using fasterq-dump. Creates one job per listed run accession, and is therefore much faster and more robust to errors when many accessions need to be downloaded.
