MetaPhlAn 3.0.4

MetaPhlAn is a computational tool for profiling the composition of microbial communities (Bacteria, Archaea and Eukaryotes) from metagenomic shotgun sequencing data (i.e. not 16S) with species-level. With the newly added StrainPhlAn module, it is now possible to perform accurate strain-level microbial profiling.

Description

MetaPhlAn is a computational tool for profiling the composition of microbial communities (Bacteria, Archaea and Eukaryotes) from metagenomic shotgun sequencing data (i.e. not 16S) with species-level. With the newly added StrainPhlAn module, it is now possible to perform accurate strain-level microbial profiling.

MetaPhlAn relies on ~1.1M unique clade-specific marker genes (the latest marker information file mpa_v30_CHOCOPhlAn_201901_marker_info.txt.bz2 can be found here) identified from ~100,000 reference genomes (~99,500 bacterial and archaeal and ~500 eukaryotic), allowing:

• unambiguous taxonomic assignments;
• accurate estimation of organismal relative abundance;
• species-level resolution for bacteria, archaea, eukaryotes and viruses;
• strain identification and tracking
• orders of magnitude speedups compared to existing methods.
• metagenomic strain-level population genomics

Installation

The best way to install MetaPhlAn is through conda via the Bioconda channel. If you have not configured you Anaconda installation in order to fetch packages from Bioconda, please follow these steps in order to setup the channels.

You can install MetaPhlAn by running

$ conda install -c bioconda python=3.7 metaphlan

For installing it from the source code and for further installation instructions, please see the Wiki at the Installation paragraph.
