A Nextstrain build pipeline that analyzes SARS-CoV-2 viral genomes to understand their evolution and spread, producing phylogenetic visualizations published at nextstrain.org/ncov. It is a Snakemake-based workflow written in Python that ingests genome data (e.g., from GISAID) and runs quality control, alignment, tree building, and clade assignment.
Use cases
- build a phylogenetic analysis of SARS-CoV-2 genomes
- track how covid virus variants evolve and spread
- run a nextstrain pipeline for viral genome data
- assign clades to my own coronavirus sequences
- visualize viral genome phylogeny over time
- reproduce the nextstrain ncov builds locally
When to choose
- you need a ready-made, maintained pipeline for SARS-CoV-2 genomic epidemiology
- you want to reproduce or extend the public nextstrain.org/ncov builds
- you have GISAID or other genome data and want phylogenetic and temporal analysis
When to avoid
- you need pathogen-agnostic phylogenetics for non-SARS-CoV-2 organisms (use nextstrain's other pathogen builds or augur directly)
- you want a simple GUI tool rather than a command-line workflow
- you lack access to genome sequence data such as GISAID downloads
