Please note that the lectures do not assume you have read the book chapters ahead of time. Unless you prefer to get a feel for the material ahead of a lecture, we suggest you instead plan to read the book chapters after the lectures, as a way to ensure you understood the material covered in the lectures, as well as to dig deeper into topics that we only cover at a high level in the lectures.

Lecture Examples

Files from the K-mers example:

• K-mers lecture notes

• dnafile.py

• Drosofila genome files
