🗝️ Features

• Seamless Integration: Execute MMseqs2 commands directly within your Python code, eliminating the need for shell scripting or external command-line tools.
• Output Parsing: Convert MMseqs2 outputs into Python objects (e.g., Pandas DataFrame, generators, dictionaries) for easy manipulation and analysis.
• High Performance: Leverage the speed and efficiency of MMseqs2 while enjoying the flexibility of Python.
• Cross-Platform: Use PyMMseqs via pip or Docker, ensuring compatibility across different environments. PyMMseqs works seamlessly on Linux and macOS.

Note: Windows users should either use Windows Subsystem for Linux (WSL) or Docker to run PyMMseqs.

🛠️ Installation

PyMMseqs can be installed in two ways: via pip (recommended for most users) or using a Docker image (ideal for reproducible environments).

Installing via pip

The pymmseqs package is currently available on PyPI. To install it, use the following command:

pip install pymmseqs

Using Docker Image

For users who prefer not to install PyMMseqs locally or want a pre-configured environment, a Docker image is available on GitHub Container Registry (GHCR).

Debian-based Image

To pull the Debian-based Docker image, run:

docker pull ghcr.io/heispv/pymmseqs:latest-debian

Note: If you want to use a specific version of PyMMseqs, you can replace latest with the desired version.

Tip: Using Docker ensures that all dependencies, including MMseqs2, are pre-installed and configured, making it ideal for reproducible workflows.

🚀 Example Usage

Here's a simple example to get you started with PyMMseqs. This example demonstrates how to perform sequence clustering and parse the results.

If you were using MMseqs2 directly in the terminal, you would run the following command to cluster sequences:

mmseqs easy-cluster human.fasta human_clust tmp --min-seq-id 0.9

With PyMMseqs, you can achieve the same result directly in Python, and parse the output to Python objects for further analysis.

from pymmseqs.commands import easy_cluster

# Perform clustering on a FASTA file (equivalent to the terminal command above)
human_cluster = easy_cluster("human.fasta", "human_clust", "tmp", min_seq_id=0.9)

# Get results as a Python generator for easy processing
cluster_gen = human_cluster.to_gen()

# Let's get the representative sequence of a cluster with more than 100 members
for cluster in cluster_gen:
    if len(cluster["members"]) > 100:
        print(f"Representative sequence of a large cluster: {cluster['rep']}")
        break
