I am starting to work with flu data and I am wondering which sources you use for clade definition?
E.g. for seasonal-flu/clades_h3n2_ha.tsv at master · nextstrain/seasonal-flu · GitHub ?
I can find some clade defining mutations in documents such as “Influenza virus characterization: summary report, Europe, November 2022” from WHO (see Publications) but not all of them.
If possible, could you provide all your source documents defining all the influenza clades?
Thanks for your help.
