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.

Dealing with low-quality genome references

Unfortunately, not all reference genomes will have the quality of Plasmodium falciparum. Apart from some model species (for example, humans, or the common fruit fly Drosophila melanogaster) and a few others, most reference genomes could use some improvement. In this recipe, we will learn how to deal with reference genomes of lower quality.

Getting ready

In keeping with the malaria theme, we will use the reference genomes of two mosquitoes that are vectors of malaria: Anopheles gambiae (which is the most important vector of malaria and can be found in Sub-Saharan Africa) and Anopheles atroparvus, a malaria vector in Europe (while the disease has been eradicated in Europe, this vector is still around). The Anopheles gambiae genome is of reasonable quality. Most chromosomes have been mapped, although the Y chromosome still needs some work. There is a fairly large unknown chromosome, probably composed of bits of X and Y chromosomes, as well...
