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 StrainPhlAn, it is possible to perform accurate strain-level microbial profiling", according to its GitHub repository. While the software stack on our clusters does contain modules for a couple of older versions (2.2.0 and 2.8) of this software, we now expect users to install more recent versions using a Python virtual environment. Wheels are available in our wheelhouse for these more recent versions of the MetaPhlAn software: 3.0.0a1, 3.0.7 and 4.0.2. You should begin by loading certain modules needed by the Python wheel,

[name@server ~]$ module load gcc blast samtools bedtools bowtie2 muscle python/3.9

after which you can create the virtual environment

[name@server ~]$ virtualenv --no-download --clear $HOME/ENV && source $HOME/ENV/bin/activate

You should then enter the virtual environment,

[name@server ~]$ source $HOME/ENV/bin/activate

update pip if necessary,

(ENV) [name@server ~] pip install --no-index --upgrade pip

and finally install the wheel,

(ENV) [name@server ~] pip install --no-index metaphlan
