rich-msa

A simple module to render colorful Multiple Sequence Alignment with rich in the terminal.

🔧 Installing

Install the rich-msa package directly from PyPi which hosts universal wheels that can be installed with pip:

$ pip install rich-msa

💡 Example

Use Biopython to load a MSA from an aligned FASTA file, and render it to the terminal:

import Bio.AlignIO
import rich
from rich_msa import RichAlignment

msa = Bio.AlignIO.read("tests/data/swissprot-halorhodopsin.muscle.afa", "fasta")
viewer = RichAlignment(
    names=[record.id for record in msa],
    sequences=[str(record.seq) for record in msa],
)

panel = rich.panel.Panel(viewer, title="swissprot-halorhodopsin.muscle.afa")
rich.print(panel)

You should get an output similar to the following picture, scaled to your terminal width:

🪛 Command-Line

If you have the rich-msa library installed from PyPI, you can use it directly to view any alignment file, provided you have Biopython installed:

$ python -m rich_msa -i tests/data/swissprot-halorhodopsin.muscle.afa

Use the -f flag to change the file format from aligned FASTA (default) to any alignment format supported by Biopython.
