ZipStrain
Fast strain-level metagenomics in three commands: map reads to BAMs,
profile them into per-position nucleotide-count tables, and compare
samples by ANI to tell whether they share a strain.

Install
Conda is the easiest path — it brings in samtools and the map aligners too:
conda create -n zipstrain -c conda-forge -c bioconda \
python=3.12 zipstrain bowtie2 samtools sylph
Or with pip (into a fresh virtual environment):
pip install zipstrain
Matrix-store comparison dependencies (compare --method matrix):
pip install "zipstrain[matrix]"
Notes:
-
With pip, install
samtoolsseparately (profiling needs it);zipstrain mapadditionally needsbowtie2andsylph(andprodigalfor--predict-genes). -
On Apple Silicon, use a native
osx-arm64Conda so dependencies install natively; the standardtorchwheel uses the MPS backend. -
Linux CUDA installs should replace Torch with the matching CUDA wheel from PyTorch:
pip install "zipstrain[matrix]" pip install --upgrade torch --index-url https://download.pytorch.org/whl/cu124
See the installation guide for full details.
