Scoring Multiple Sequence Alignments with Python

PyMSA is an open source software tool aimed at providing a number of scores for multiple sequence alignment (MSA) problems. This project is a development of the students of the third course students of the degree on Bioinformatics of the E.T.S. de Ingeniería Informática of the University of Málaga.

Features

The scores that are currently available are:

• Sum of pairs,
• Star,
• Minimum entropy,
• Percentage of non-gaps and
• Percentage of totally conserved columns.

Downloading

To download PyMSA just clone the Git repository hosted in GitHub:

$ git clone https://github.com/ajnebro/pyMSA.git
$ python setup.py install

Alternatively, you can install with pip:

$ pip install pyMSA

Requirements

PyMSA has been developed with Python 3.6.0 :: Anaconda 4.3.0 (x86_64).

To install all dependencies use:

$ pip install -r requirements.txt

Usage

An example of running all the included scores is located in the scoringExample file.

History

Last changes (July 2017)

• pyMSAScoring project is now renamed to pyMSA!
• All the scores are now computed using a list of sequences instead of a list of pairs.
• Tests for Percentage of non-gaps added.
