Kraken is a metagenomic mapping tool that calculates abundances of taxonomic labels in a mixed sample. To use it you can load the existing module kraken2kraken/2.1.1 . For a pre-built database refer to the section below.
...
- Viroids: 95 genomes (95 contigs), 0.03mb.
- Viruses: 27827 genomes (67295 contigs), 939.23mb.
Update: Two newer databases have been uploaded to:
One is taken from Ben Langmeads K2 Index page, the other (plus) is custom built containing all NCBI clades and in addition a selection of interesting gut microbiome species, a mouse genome and representative genomes from the fungi and protozoa clade even if they are not marked as "full genome" or "chromosome". The folders contain .txt files giving a detailed breakdown of the contents.
