This is the homepage for 27820 - Ph.D course in Medical Biofilm Techniques.

Note: This page will be continuously updated and you should not expect all manuals to be here before a few days before the course starts.

Here you can find the general description of the course: DTU Course base


General information

The course will start August 10th 2014 at 9.00 am in room 056 (ground floor) at DTU, Building 301. For directions, please follow this link.

DIY Sandwich lunch will be provided Sunday Aug 10th, Saturday Aug 16th and Pizza Lunch on Sunday 17th.

General Time Table: Download (Updated Aug 11th)
List of Speakers and titles of talks: Download (note: preliminary list - times are correct, some titles are missing)

There will be wireless network available. The network is connected to the European EDUROAM collaboartion in which most Western European universities participate. Check with your home university IT department if you can use EDUROAM and get instructions there. Otherwise we will issue a guest login (but EDUROAM is much easier).
Please note
  • Some files require a password to download. This should have been provided to you along with the link to this page. If for some reason you have not received the password, please e-mail Claus Sternberg.
  • Manuals and other materials marked with "(PRINTED)" will be given in hard copy at course start

FACEBOOK: We have a Facebook group for present and past participants and instructors/speakers which you can join if you like. Go here: and apply for membership. Note: The group is not terribly active, but who knows, perhaps someone will make it more interesting some time... :-)


Here we will keep you updated on changes of schedule, and other things you need to know (e.g. where to find result data files)

04.08.2014. Eduroam and iPass
You may want to check out iPass as well as Eduroam. Link to relevant information
04.08.2014. Regarding the student presentations
We will try to do them in the periods of waiting. There will be several occasions where more teams are waiting, e.g. to get to the microscopes. In these periods we suggest the teams not active at the instruments can do their presentations for the other waiting teams. This of course means that you will not hear all presentations, but still most of them.
04.08.2012. Bring your own samples
For the free exercise you can bring your own samples from home. It can be some bacterial strains you work with in your projects, or e.g. a soil sample from home, or a swap from your bath room sink. The oly requirement is that if you bring bacterial samples that they are non-pathogenic.
11.08.2014. A new version of the time schedule has been uploaded
The Timing of the FISH ex (BF system 2) has been changed.
12.08.2014. Talks
The final schedule for speakers has been uploaded.
14.08.2014. Comstat
New version of COMSTAT uploaded.
19.08.2014. Presentations
All group presentations from Sunday now uploaded.


Here we will put changes and errors we detect in the documentation. This document will be updated as the course is progressing (latest update date is shown.

Download Software

Comstat 2

First - go to and get all nessesary support files. Please read the instructions in the HOW-TO-INSTALL document.

When all that has been done, get the comstat2 program file (Comstat2_.jar): here .

New version of comstat - Download here (to be installed on top of old files)

Note: When you download the comstat2 program file we imply that you accept the license conditions which are set out on, namely:

  • That you will not distribute the program to others, but refer them to where they can obtain a copy for free
  • That you will acknowledge the use of Comstat2 in any publication that will be written using Comstat2 generated data in any form.

Imaris 7.6

Download the program file appropriate for your system

Install the program file. Save the license file somewhere on your computer and when you start Imaris, use the browse button in the license dialog box shown to point to the demo license file.

(Note: the first steps are mac-specific but the rest is common to PC and Mac).

The demo license is valid until the end of August 2014. If you need testing after that, please contact Bitplane.
See also: Installation Instructions on

In order to enable Imaris to communicate with MATLAB, ImageJ and Java, you need to download and install these two helper programs:
Note: In this course it is unlikely that you will need the MATLAB/Java functionality of Imaris. But in case you want to check it out we include the links.

and the MATLAB Compiler Runtime (MCR). Please download the MCR version appropriate for your system:

You may also want to download SceneViewer which allows you to show Imaris stacks without a full license. You will, however, need to obtain a permanent license directly from Bitplane, Inc. The program will show how to get that when the demo license has expired.

Brochures for Imaris:

Zeiss ZEN File Viewer

You can download the viewer program for native Zeiss confocal image stacks here

Leica LAF Viewer

You can download the viewer program for native Leica confocal image stacks here
