.. class:: infomark

**Input example:** You can try out MetaPhlAn using the synthetic dataset (250,000 reads) available at: http://huttenhower.sph.harvard.edu/sites/default/files/LC1.fna . There is no need to download the file, you can just copy-and-paste the dataset address in the "Upload File" module inside the "Load Data" link here in the left panel.

.. class:: infomark

**Computational time:** Unless the server is overloaded, you should expect the tool to process ~10,000 reads per second. The synthetic metagenome linked above (250,000 reads) should take no more than 30 seconds to complete.

**What it does**

MetaPhlAn (Metagenomic Phylogenetic Analysis) is a computational tool for profiling the composition of microbial communities from metagenomic shotgun sequencing data. MetaPhlAn relies on unique clade-specific marker genes identified from reference genomes, allowing orders of magnitude speedups and unambiguous taxonomic assignments.

Although MetaPhlAn can use both BlastN and BowTie2 in the read-to-marker mapping step, this Galaxy module uses only BowTie2 for computational reasons. 

For additional information about MetaPhlAn and the MetaPhlAn command line package, please refer to http://huttenhower.sph.harvard.edu/metaphlan or to the paper reported below. Please notice that most of the additional parameters that can be tuned with the command line version are set here to the default values.

---------

**Inputs**

The input file must be a multi-fasta file containing metagenomic reads loaded with the "Get Data" module in the left panel. Reads can be as short as ~40 nt although lengths higher than 70 nt are recommended. 

A synthetic metagenome you can use as sample input is available at http://huttenhower.sph.harvard.edu/sites/default/files/LC1.fna

**Outputs**

The output is a two column tab-separated plain file reporting the predicted microbial clades present in the metagenomic samples and the corresponding relative abundances. 

All taxonomic levels from domain to species will be reported and higher taxonomic levelis contain the sum of the abundances of its taxonomic leaf nodes (usually species) and, possibly, some lower level "unclassified" clades.
