New version of PR2 that now includes the eKOI coi database recently published.
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
