Bioinformatik: It og Sundhed - course programme, winter 2010


The curriculum consists of hand-out notes and the computer exercises themselves. There is no formal text-book. All needed reading material will be available online, linked directly from this page. The material can be read on a day-to-day basis.

4 hours written exam.

Where and when:
The Technical University of Denmark, Lyngby Campus, Building 208, room 062 and 060 (From Jan 6'th - 27 Jan). Directions on how to get to DTU (Lyngby) and a map of the buildings are found here: DTU Directions. Map of the DTU buildings here.

The course runs for 10 weeks with lectures and exercises 1 day a week from 9:15 to ~16:00 (or wheneven the computer execersis of the day has been completed).
The exam will be Jan 27'th, 2011 in room 060 - also in the basement close to room 062.
Each day starts with lectures in the morning, and concludes with computer excersices in the afternoon. Teaching will be in danish, but slides and readings are most often in english.

Hardware / Software used

The computer exercises can be executed from any internet connected computer (Mac, Linux, Windows) with a modern browser (e.g. FireFox, Safari or a recent version of Internet Explorer - a browser which supports tabs is recommended) and Java installed. Java is used in some exercises to run visualization software. Link: A computer is necessary for most of the exercises, therefore bring your own. It is possible to borrow a computer at CBS. In that case send a mail ASAP to the course coordinator.

We recomment the JEdit text editor for use on sequence files, since it is well suited for this purpose and is platform independent. Link:

For the protein structure exercise the PyMOL software (also cross-platform) will be used. Main link:

Room: Teaching will be in building 208, room 062 and 060 (downstairs) - unless another place in announced for that teaching-day
