Acerca de este curso: We will learn computational methods -- algorithms and data structures -- for analyzing DNA sequencing data. We will learn a little about DNA, genomics, and how DNA sequencing is used. We will use Python to implement key algorithms and data structures and to analyze real genomes and DNA sequencing datasets.

SEMANA 2
Preprocessing, indexing and approximate matching
In this module, we learn useful and flexible new algorithms for solving the exact and approximate matching problems. We'll start by learning Boyer-Moore, a fast and very widely used algorithm for exact matching

Calificaciones y revisiones
I loved this course. The material was really interesting and it was well taught. The assignments were excellent as well.
Very good lectures. Some of the homework assignments were kind of hard though (and no help in the discussion forums).
Helpful material for DNA Sequencing and number crunching.
Well taught, I suggest a background in Python to make things more enjoyable.

I enjoyed the introduction to some of the algorithms used in genomics... and hope to explore these further in my career.
