We have added more than 900 new GenBank sequences to the RCC database that are linked to the web page of the corresponding strains.

New version of PR2 that now includes the eKOI coi database recently published.
pr2-database.bsky.social The PR2 database @pr2-database.bsky.social · 14d
Version 5.1.1 of the PR2 database has been released.

The major novelty is the inclusion of the recently published eKOI database (coi gene- doi.org/10.1093/data...) in the web interface. The 18S rRNA database is not changed so you can use 5.1.0 or 5.1.1 for metabarcode annotations

metaPR2 version 3.0 has just been released.

Here are the major changes:
- Metabarcodes (ASVs) are now annotated with the latest version of the PR2 reference sequence database (5.1.0).
- 8 new published datasets have been added from the Arctic and from the South West Pacific.

The following statement is utterly misleading "The cost of this venture pales in comparison to running a scientific research vessel, while yielding far more information..." A bunch of random measurements will never replace a carefully planned cruise with a very large number of metadata.
