SARS-CoV-2 lineage assignment tool


Pangolin (Phylogenetic Assignment of Named Global Outbreak LINeages) is a tool provided by the Rambaut group as part of the COG-UK consortium for the assignment of lineage names to SARS-CoV-2 genomes.


Pangolin uses an internal machine learning-based method called Pangolearn to assign a lineage to query genomes. For a full description of how lineages are assigned see the description of Pangolearn:

Downloads, genome reports, and collections

The complete output is provided by the CSV download menu in the Genome Browser and the Collection View. It is also shown in the Genome Reports for SARS-CoV-2 genomes (below) along with links to external descriptions of the lineages.

Browsing lineages

Pangolin lineages are displayed next to SARS-CoV-2 genomes in the Genome Browser and in the Typing table of collections. It's also possible to find genomes with a particular lineage in the Genome Browser by selecting "Betacoronavirus" in the "Genus" filter, "Severe acute respiratory virus" in the "Species" filter, and then "subsp. SARS-CoV-2". This enables the "Lineage" filter, allowing genomes from particular lineages to be selected.
