@HELP_HEADER@

This tool corresponds to the main tool in HUMAnN pipeline:


1. Taxomonic prescreen

    Reads are mapped (with MetaPhlAn) to clade-specific marker genes to rapidly identify community species

2. Pangenome search (nucleotide search)

    Reads are mapped (with Bowtie2) to pangenomes of identified species

3. Translated search
    
    Unclassified reads are aligned to a comprehensive and non-redundant protein database

4. Gene family and pathway quantification

    - Gene abundance estimation

        Mapping results are processed to estimate per-species and community total gene family abundance, weighting by
        
        - alignment Quality
        - gene length
        - gene coverage

    - Per-species and community-level metabolic network reconstruction

        Genes are mapped to metabolic reactions to identify a parsiomonious set of pathways that explains each species' observed reactions

        Pathway abundance and coverage are quantified by:

        1. optimizing over alternative subpathways
        2. imputing abundance for conspicuously depleted reactions


Inputs
======

HUMAnN can start from a few different types of input data each in a few different types of formats:

- Quality-controlled shotgun sequencing reads
    
    This is the most common starting point : A metagenome (DNA reads) or metatranscriptome (RNA reads)

- Pre-computed mappings of reads to database sequences
    
- Pre-computed (typically gene) abundance tables


HUMAnN uses 3 reference databases
Locally cached databases have to be downloaded before using them (using the dedicated tool). Custom databases can also be used after upload.

Outputs
=======

HUMAnN creates three output files:

- Gene families and their abundance
- Pathways and their abundance
- Pathways and their coverage

Ten intermediate temp output files can also be retrieved.
