Chapter 3 Software for class

Objectives:

  1. To familiarize ourselves with the main software used in class
  2. To install programs used for basic computational biology
  3. To perform basic tests of functionality of these programs

As I mentioned in the previous chaopter, we are going to use R, RStudio and the basic UNIX command line for our exercises, as well as atom, a basic text editor that’s widely used in programming to view and edit files.
