new GTDB databases for rs220: draft

[ctb]

Note: not yet final

release rs220 from GTDB: https://data.ace.uq.edu.au/public/gtdb/data/releases/release220/

sourmash databases constructed by @ccbaumler 🎉 using directsketch -

• gtdb-rs220-k21.zip - 17 GB
• gtdb-rs220-k31.zip - 17 GB
• gtdb-rs220-k51.zip - 17 GB
• gtdb-rs220.lineages.csv.gz - 13 MB

Note: The databases are missing approximately 200 genomes that have been deprecated/suspended by GenBank.

Questions/thoughts

• should we release a higher scaled / smaller download?
• probably no need for an SBT or LCA any more
• what do we do about the missing genomes?
• do we remove the missing genomes from the lineages file?

Are there sketches of a reduced genome-representatives version of the GTDB rs220 release? Not complaining if not. Thank you, @ccbaumler, for what you've provided here!

Yup! Representative genomes have been sketched. I will be meeting with @ctb next week to get everything set up.
