Ways to Uninstall or Install bwa on Ubuntu 22.04

Updated: September 2, 2022

BWA is a software package for mapping low-divergent sequences against a large reference genome, such as the human genome. It consists of three algorithms: BWA-backtrack, BWA-SW and BWA-MEM. The first algorithm is designed for Illumina sequence reads up to 100bp, while the rest two for longer sequences ranged from 70bp to 1Mbp. BWA-MEM and BWA-SW share similar features such as long-read support and split alignment, but BWA-MEM, which is the latest, is generally recommended for high-quality queries as it is faster and more accurate. BWA-MEM also has better performance than BWA-backtrack for 70-100bp Illumina reads. In this tutorial, I will show you how to install bwa on Ubuntu 22.04.

Prerequisites to install

  • OS: Ubuntu 22.04 or older Ubuntu versions
  • Privileges: Make sure that you can run the sudo commands line.
