Hello,  
I am analyzing an algal genome (microalgae, eukaryote) and the current Kraken2 databases available in Galaxy Europe only contain Bacteria/Archaea/Viral/Human.  
Because of this, my eukaryotic sample cannot be classified properly.  
Could you please add a Kraken2 database that includes Eukaryota (e.g. RefSeq eukaryotes, protists, or algae genomes)?  
This will greatly help for contamination screening in de novo assembly cases.  
Thank you.

Hi @berlianagita,

Galaxy Europe provides several Kraken2 databases with Eukaryota data, for example, core\_nt.

Hope that helps.

Kind regards,

Igor
