HUMAnN
Description
HUMAnN is a pipeline for efficiently and accurately profiling the presence/absence and abundance of microbial pathways in a community from metagenomic or metatranscriptomic sequencing data. This process (functional profiling) aims to describe the metabolic potential of a microbial community and its members.

Availability
Versions available in Puhti: 3.0.1, 3.6, 3.8
Usage
In Puhti, HUMAnN is installed as containerized application. To activate it, run command:
module load humann
humann
By default HUMaN tries to check and update the MetaPhlAn database every time it's run. This will fail with containerized installation, so you will need to add command line option:
--metaphlan-options "--offline --bowtie2db /path/to/db"
To use CSC provided database use:
--metaphlan-options "--offline --bowtie2db $MPA"
CSC provides default versions of the HUMaN databases. You can use them by specifying:
--nucleotide-database $HUMANN_NUC
--protein-database $HUMANN_PROT
