Strain Genome Explorer: a tool suite for tracking and characterizing low-abundance strains.

StrainGE: Strain-level Genome Exploration

StrainGE is a set of tools to analyse the within-species strain diversity in bacterial populations. It consists of two main components: 1) StrainGST: Strain Genome Search tool, a tool to find close reference genomes for strains present in a sample and 2) StrainGR: Strain Genome Recovery, a tool to perform strain-aware variant calling at low coverages.

Dependencies

Python packages

• Python >= 3.7
• NumPy
• SciPy
• matplotlib
• scikit-bio >= 0.5
• scikit-learn >= 0.24
• pysam
• h5py
• intervaltree

Bioinformatics tools

• bwa
• samtools
• mummer

Installation

Python Package Index

pip install strainge

Warning: NumPy already has to be installed otherwise the above command will fail. You'll have to make sure all tools like bwa, samtools and mummer are installed as well.

Conda

1. Install Anaconda or miniconda (if not already present on your system)

2. Create a new environment:

   conda create -n strainge python=3

3. Activate the environment:

   source activate strainge

4. Enable bioconda and conda-forge channels:

   conda config --add channels bioconda
   conda config --add channels conda-forge
   

5. Install StrainGE:

   conda install strainge

Optional tip: also consider installing mamba before installing StrainGE for much faster conda operations.
