Kraken 2 tutorial

Here I will try to see what kind of bacteria and viruses lie within the RNAseq of a clade of nematodes. The clade is the Tylenchida, a clade with diverse lifestyles, but most interestingly, lots of parasites.

Kraken has a lot of standardized databases that can be downloaded, though the more species/clades you include, the longer it takes to make the kraken database.

Lots of great information can be had at the Kraken2 wiki

Step 1: Build an appropriate kraken2 database

Note that this is a slight hack to the normal database build, but allowed the build

Modify download_taxonomy.sh

#download taxonomy data from ncbi
module load GIF/kraken2
#kraken2-build --download-taxonomy --db NematodeViral
#This should have worked, but NCBI removed a couple files from their ftp site (est and gss)
Had to modify the download_taxonomy.sh script to skip downloading these files.


vi download_taxonomy.sh
########
Changed from
TAXONOMY_DIR="$KRAKEN2_DB_NAME/taxonomy"
if [ -z "$KRAKEN2_PROTEIN_DB" ]

To
for subsection in gb wgs
if [ -z "Viral" ]
########
sh download_taxonomy.sh

Prepare the genomes you’d like to add to your kraken database

You will have to look up the taxonomy ID and add this to each fasta headers as I have done below. i.e. (>sequence”|kraken:taxid|390850)

Note that nematode genomes are small, this takes much longer for larger genomes.

I took these files, added the species name to the fifth column, removed those entries that had fewer than 100 reads allocated, kept only genera, species, and subspecies, and then concatenated all files for a network in cytoscape.
