At the end of the day, you will be send home with some challenges to do yourself and additional learning material. As a homework, you may write a program to analyze your own data. On the second day of the training, we will look to the solutions of the homework and explain the results of the tasks. We will dig a little deeper in good programming hygiene, and create some more complex scripts using regexes and reading in files. By the end of the day, a firm basis for perl programming should be established to allow further self-study.
