Bioinformatics with Python Cookbook - Third Edition

By: Tiago Antao

Overview of this book

Bioinformatics is an active research field that uses a range of simple-to-advanced computations to extract valuable information from biological data, and this book will show you how to manage these tasks using Python. This updated third edition of the Bioinformatics with Python Cookbook begins with a quick overview of the various tools and libraries in the Python ecosystem that will help you convert, analyze, and visualize biological datasets. Next, you'll cover key techniques for next-generation sequencing, single-cell analysis, genomics, metagenomics, population genetics, phylogenetics, and proteomics with the help of real-world examples. You'll learn how to work with important pipeline systems, such as Galaxy servers and Snakemake, and understand the various modules in Python for functional and asynchronous programming. This book will also help you explore topics such as SNP discovery using statistical approaches under high-performance computing frameworks, including Dask and Spark. In addition to this, you’ll explore the application of machine learning algorithms in bioinformatics. By the end of this bioinformatics Python book, you'll be equipped with the knowledge you need to implement the latest programming techniques and frameworks, empowering you to deal with bioinformatics data on every scale.

Accessing Galaxy using the API

While Galaxy’s main use case is via an easy-to-use web interface, it also provides a REST API for programmatic access. There are interfaces provided in several languages, for example, Python support is available from BioBlend (https://bioblend.readthedocs.io).

Here, we are going to develop a script that will load a BED file into Galaxy and call a tool to convert it to GFF format. We will load the file using Galaxy’s FTP server.

Getting ready

If you did not go through the previous recipe, please read the corresponding There’s more... section. The code was tested in a local server, as prepared in the preceding recipe, so it might require some adaptations if you run it against a public server.

Our code will need to authenticate itself against the Galaxy server in order to perform the necessary operations. Because security is an important issue, this recipe will not be totally naive with regard to it. Our script will be configured...
