This tutorial was created for participants in a bioinformatics workshop organized by Janusz M. Bujnicki for the EURASNET consortium in 2010. I would like to thank the organizers and all course participants, as well as Joachim Jacob for reviewing the material. Further thanks go to the German Academic Exchange Service (DAAD) for financial support.
Special thanks go to Allegra Via for using this tutorial in our course over the years, and to Pedro Fernandes for suggesting publication via Gitbook.
