Latest revision as of 14:30, 15 November 2024
General information
Where and when
Lectures plus subsequent exercises will take place every Tuesday afternoon during the semester, starting Tuesday Sep 3 at 13:00.
Lectures will be from 13:00 to approx. 14 in Aud. 54, building 208, and the exercises will then take place in the group rooms ALC1/001, ALC2/011, and ALC3/002, also in building 208.
Teachers
- Henrik Nielsen — Associate professor, course responsible.
- Carolina Barra Quaglia — Associate professor, course responsible.
- Rasmus Wernersson — External associate professor.
Teaching assistants
- Hanxi Li — PhD student
- Myeonghyun Yoou — Industrial PhD student
Course content
In this course, a large emphasis is placed on the practical usage of bioinformatics databases and tools. A typical lecture will present the theoretical aspects of the topics of the day — sometimes including a small group exercise using pen and paper — and last about an hour. The rest of the time will be spent on practical computer exercises, where the teachers and teaching assistants will be ready to help.
See also the course base about 22111.
Curriculum
There is no formal textbook. The curriculum consists of the exercise guides, supplemented with various papers and chapters which will be made available on this homepage or on DTU Learn. Please note that all exercise guides are mandatory curriculum — including the answers to the exercises which will be made available on DTU Learn after each exercise.
Computers
Hardware
You must bring your own laptop to the exercises, and it must be able to connect to DTU's wireless network. The type of computer / operating system is not important; Windows, Mac or Linux will all work fine. An iPad or an Android tablet, on the other hand, will not be good enough. A Chromebook will also not be enough (unless you have succeeded in installing a Linux distribution on it, but in that case we assume you know what you're doing).
In some of the exercises ("PDB/PyMOL", "Malaria vaccine", and "Old exam questions"), you will work with the molecular visualization program PyMOL. This is rather difficult to control by a touchpad, so please remember to bring a mouse. The mouse should have two buttons plus a scroll-wheel.
Software
- Most importantly: an updated internet browser (e.g. Google Chrome, FireFox, Opera, Edge, or Safari for Mac only). NB: You must have more than one browser installed; Safari for Mac or Edge for Windows may have glitches with some bioinformatics websites, and in those cases it is important to be able to switch to an alternative browser.
- A plain text editor for working with, e.g., sequence files. We recommend Geany, which you can download for free from https://geany.org/. You will find some tips and installation instructions in the first exercise.
Other software will be installed during the exercises.
Note: Previously in the course, we have used some java-based software; but it is our experience that new Macs (with M1 or M2 CPUs) often have problems with java. Therefore, we have replaced these programs with other options:
- Geany has replaced jEdit, see the exercise in plain text files.
- SeaView has replaced Jalview, see the exercise in multiple alignments.
- The website iTOL has replaced the software FigTree, see the exercise in phylogenetic trees.
Be aware that if you are working on old exam sets, they may refer to the old software.
Hand-ins
As preparation for the computer-based exam, each participant or group must write a "logbook" with answers to the questions posed in the exercise guides. After the exercise, you should upload the logbook to DTU Learn.
NB: All hand-ins are per definition group hand-ins. If you work alone, you must form a "group" of one person.
You decide which software you prefer for writing the logbook — e.g. Microsoft Word, LibreOffice (free), Apache OpenOffice (free), Pages for Mac, Google Docs or similar. You should be able to insert screenshots in the logbooks for documentation purposes. Microsoft Word has a built-in screenshot tool. Both Windows 10/11 and Mac OS also have dedicated screenshot tools.
Regardless of your choice of writing software, the result must be handed in as a PDF file. LibreOffice and Google Docs can make PDFs directly. MacOS and Windows 10/11 have built-in functions for converting any printable file to PDF.
Please do not copy the questions from the exercise guide to your logbook. The hand-in module on DTU Learn has a system for plagiarism detection, which will raise an alarm if significant portions of your hand-in are identical to documents found on the internet — and that includes the exercise guides.
In case you don't finish the exercises Tuesday afternoon, there is still a chance to hand in — the deadline for handing in at Learn is Thursday at 13:00 each week. The answers to the exercises will become visible at the same moment (Thursday at 13:00). You should read the answers carefully and compare with your own answers.
We do not offer individual feedback on the hand-ins, but we will give a collective feedback before the lecture the next Tuesday, where we address any common mistakes there may have been.
NB: The hand-ins do not affect your grade — they are mainly meant as a preparation for the exam. They are also a means for us to check the understanding of the teaching; if we can see that many participants have made the same mistake, we will try to explain the issue better at the beginning of the next lecture.
Exam
The 22111 exam is electronic; i.e. you must bring your own computer, and you will not get a paper copy of the questions. The questions will be made available as a PDF file on the DTU online exam system. The only accepted hand-in format is PDF.
Just like in the weekly hand-ins, we kindly ask you: Please don't copy the questions in your answer document — that might result in the answer being flagged as plagiarism.

Evaluation and feedback
We will be very happy to receive comments, suggestions, criticisms, or praise at any time during the semester. You can:
- send them by email to the teachers, or
- write them under "General feedback" in "Discussion" in DTU Learn.
If somebody writes a message in "Discussion", you can comment on it. If you see a message you agree on, please comment "Agree!" so that we can see that it is not just one person's opinion.
In addition, we will conduct a mid-term evaluation in DTU evaluation.
