Plant Kraken2 database



I would like to know if anyone has managed to build a Plant Kraken2 database? I tried to build one but I get an error during the building process:

kraken2-build --build --db kraken2 --threads 64
Creating sequence ID to taxonomy ID map (step 1)…
Sequence ID to taxonomy ID map already present, skipping map creation.
Estimating required capacity (step 2)…
/home/ubuntu/volume1/chick_genome/kraken2/scripts/ line 101: estimate_capacity: command not found
xargs: cat: terminated by signal 13

If some one has a prebuilt database or can help me rectify this, this will be so great!!

I am using a Swansea server
