Bioinformatics

Genomics and DNA analysis

17 September 2019

The main subject is “metagenomics”. We will learn how to handle the output of DNA sequencing machines, how to assemble the chromosome, how to find genes and how to determine the probable function of the proteins they encode. If time allows, we will also study phylogenetic trees and microarray analysis.

Classes are held each week on Tuesdays 13:00–17:00 (at the Physics Dept. Computer Lab), and on Fridays at 14:00-17:00 (at Astronomy Dept. Computer Lab). Most of the practice is done on Linux servers, so you may be interested in other courses with that subject.

This page will be updated during the semester. Please check it regularly. Also, please register yourself at the course forum, at https://groups.google.com/d/forum/iu-bioinfo. You can also participate writing an email to .

Classes

Here you find the slides that have been used in classes. Notice that usually they are not published immediately, so you better take good notes. We recommend taking notes with pen and paper using the Cornell Method.

Homework

All homework should be sent to andres.aravena+bioinfo@istanbul.edu.tr before the deadline to get a grade. Use this address only for homework and exams, since it is processed automatically and I do not see any question sent there. Send your questions to the forum instead.

Send your answers always, even if they are incomplete or wrong. I adapt the course based in your answers.

Bibliography

These are some of the papers we want to read and understand during this semester. The most important ones are marked in bold face. Start by reading those
