+@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 database 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.
