SARS-CoV-2 workflow: nextclade.tsv.zst description

The documentation page SARS-CoV-2 workflow > Remote inputs mentions a file nextclade.tsv.zst which sounds intriguing. In my imagination, it is the output from processing all the sequences.fasta.zst output through the nextclade CLI. I can further imagine it is updated when there are changes to the pango designations, using the “nightly” build.

My imagination can run wild at times, but there doesn’t seem to be any further info available on that file. What does it contain, and how often is it updated?

this file does exist: https://data.nextstrain.org/files/ncov/open/nextclade.tsv.zst

But I would have to check how often the entire thing is rerun with the latest datasets. Certainly not the nightly build, but possibly the latest release.

It should be re-run from scratch whenever the dataset changes:

Thanks for the clarification Richard.

I’ve since spotted a column Nextclade_pango in the metadata file, which looks like it already holds the lineages output from Nextclade? Using that would be far more efficient at my end, for projects where I don’t need the other Nextclade output.

But it seems to use the latest released version of Nextclade, e.g. the latest lineage shown is SY.1.

Is there any way to make the Nextclade releases more frequent? Or point this pipeline at the Nextclade nightly builds?
