Hi,

I am trying to install and run Kraken for a metagenomics project. I have installed Kraken, however it requires a dependent database to be built as well. I am trying to build the database following their manual, where I am supposed to run:

kraken-build --standard --db dir/dbname

However I am getting the following error: dir/kraken/0.10.5/check_for_jellyfish.sh: line 27: jellyfish: command not found

Has anyone else faced similar problems? What am I supposed to do?

Thanks, Payal

Have you installed jellyfish as the requirements state?

If you install using the conda package for Kraken you the correct version of Jellyfish (v1).
