== General information ==

=== Where and when ===
Lectures plus subsequent exercises will take place every Tuesday afternoon during the semester, starting '''Tuesday Feb 1 at 13:00'''.

Lectures will be from 13:00 to approx. 14 in '''building 306, auditorium 32''', and the exercises will then take place in '''building 210, rooms 142+148 and 112+118'''.

=== 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 [http://kurser.dtu.dk/course/22111 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. [http://www.google.com/chrome Google Chrome], [http://www.mozilla.com/ FireFox], [http://www.opera.com/ Opera], [https://www.microsoft.com/edge Edge] for Windows or Mac OS, 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.
# '''Java''' runtime engine is needed for running some of the software we use in the course, including jEdit (see below). Download from here: https://adoptium.net/ - choose Temurin JDK 17.
#* '''NOTE:''' Oracle java 8 from https://java.com/en/ is NOT good enough for jEdit anymore. jEdit version 5.6 and later needs java 11 or higher which is available from the above link (and from a few other places). Temurin JDK is open source and free, even for commercial use, which is not the case for Oracle java anymore.
#* '''IMPORTANT TIP''' for Windows users: You need to enable the sub-feature named "set JAVA_HOME variable" when installing Temurin JDK.
# A plain text editor for working with, e.g., sequence files. We recommend '''jEdit''', which you can download for free from http://www.jedit.org. If you experience unsolvable problems installing or running jEdit, there are alternatives, e.g. [http://geany.org/ Geany].
#* '''NOTE:''' The jEdit developers have not signed the installation package, therefore both Windows and MacOS will complain when you first attempt to install it, and you have to insist that it is OK to run the program. For Macs, this is a bit complicated, see the instructions in [[ExJEdit#Download_and_Install_jEdit|the exercise guide]].
Other software will be installed during the exercises.

=== 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.


You decide which software you prefer for writing the logbook — e.g. Microsoft Word, [http://www.libreoffice.org/ LibreOffice] (free), [http://www.openoffice.org/ Apache OpenOffice] (free), Pages for Mac, [https://docs.google.com/ 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 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 have built-in functions for converting any printable file to PDF. Users of earlier versions of Windows must install a separate program. Several free alternatives exist, e.g. [http://www.primopdf.com/ PrimoPDF]. (It can be a good idea to install PrimoPDF even for Windows 10 users, it provides some extra options and the resulting files take up less space).

'''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.

'''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 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.

All aids are allowed at the exam; you can bring any books, papers or notes. You will have '''open access to the internet''' which includes all the materials and websites we have used during the course. You are also allowed to search information on Google, Wikipedia, etc., but you are ''not'' allowed to communicate with others through e-mail, Facebook, chat, or file sharing websites. The internet traffic will be logged during the exam to ensure that these restrictions are kept.

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.


=== DTU Learn & Inside ===

Link to this year's DTU Inside group: https://cn.inside.dtu.dk/cnnet/element/653095/frontpage

=== 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 the DTU Inside group (found in the Course content menu)
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 [https://evaluering.dtu.dk/ DTU evaluation].
