Hello,

I am trying to annotate H1N1 sequences uysing nextclade web version and the ref dataset of 2019, but when I download the tsv output annotation file, I cannot find columns for short clade and legacy-clade. The only available column is the clade column. Is it an update of nextclade or an issue ?

How can I access to the short clade annotation?

Thank you for your help.
