GBIO0009-1: Topics in bioinformatics 2015-16

In this course an introduction to the bioinformatics discipline is given. We do so by introducing the students to several analysis work flows corresponding to different research questions.

The course is in part based on interactive ex-cathedra lectures and in part on interactive practical sessions. The exercise sessions allow students to become familiar with the theoretical concepts introduced during the theory classes. They prepare students to successfully carry out their homework assignments.

Exam information

The exam is open book. This written exam will count for 40% of the final mark.

Anouncements

• 09 Sept 2015.Bring PC to the class of Sept 22nd. We will install R on it. In this course you will extensively use R for your practical assignments

• 03 Nov 2015.No classes this week. Enjoy your holiday and superb weather.

• 26 Nov 2015.Next week we will have a guest lecture from Benoit Charloteaux on systems biology and PPI networks. The biases and problems in use of biological data in research will be presented as a case study

• 2 Nov 2015.The exam is fixed to January 4,2016. During the next class, we can discuss whether you prefer to have the exam on a later date. All students need to agree. Survey will be distributed.
