pip install sequana

Then, just install this package:

pip install sequana_multitax

Usage

sequana_pipelines_multitax --help
sequana_pipelines_multitax --input-directory DATAPATH  --databases toydb

For the database, you will need to provide your own databases. You can check out the documentation of kraken. The toydb here above is shipped wit sequana and should work for demo. See sequana_taxonomy standalone for more help and information. You can also checkout the sequana documentation (kraken module)

This creates a directory with the pipeline and configuration file. You will then need to execute the pipeline:

cd multitax
sh multitax.sh  # for a local run

This launch a snakemake pipeline. If you are familiar with snakemake, you can retrieve the pipeline itself and its configuration files and then execute the pipeline yourself with specific parameters:

snakemake -s multitax.rules -c config.yaml --cores 4 --stats stats.txt

Or use sequanix interface.
