FieldTrip workshop in Oslo

Where

RITMO Centre for Interdisciplinary Studies in Rhythm, Time and Motion
Forskningsveien 3A
0373 Oslo
Norway

When

Wednesday June 12th - Friday June 14th 2019

Who

The RITMO Centre is the local organizer. Sabine Leske and Alejandro Omar Blenkmann are in charge of the local organization. Lau Møller Andersen (Karolinska Institute, Stockholm) and Britta Westner (CFIN, Aarhus University) are the lecturers.
RITMO Centre affiliates have priority. There is room for ~30 participants. When the local organizers have assessed how many RITMO affiliates are attending, the workshop will be open to external participants if room is left.

There will be room for ~30 participants. RITMO centre employees and students have priority.

The data used for the hands-on sessions

During the hands-on sessions we will use a task EEG dataset recorded in a language experiment.

The data will be provided on a USB stick during the hands-on sessions. You can also download the data from our FTP server.

Installing FieldTrip and setting up MATLAB

For the hands-on sessions you have to start MATLAB. To ensure that everything runs smooth, we will work with a clean and well-tested version of FieldTrip that is distributed on a USB stick, rather than the version you might already have installed. Furthermore, the tutorial data does not have to be downloaded but will also be distributed on the USB stick.

  1. Copy the contents from the USB stick to your computer
  2. Unzip the fieldtrip-xxxxxxxx.zip file.
  3. Unzip the “data.zip” file, you should place the contents in the same directory, e.g. in a newly created directory called ‘toolkit’.

Depending on the unzip program you are using (e.g. Winrar), the name of the zip file might also appear as directiory, resulting in path_to_directory/fieldtrip-xxxxxxxx/fieldtrip-xxxxxxxx, i.e. the FieldTrip directory in a FieldTrip directory. Please fix that by moving all files one level up.

After copying all files to your computer and unzipping then, you start MATLAB. To ensure that the right version of FieldTrip is used, and not another version (such as the one included in SPM or EEGLAB), you type in the MATLAB command window

restoredefaultpath
cd path_to_directory/fieldtrip-xxxxxxxx
addpath(pwd)
ft_defaults

Please do NOT use the graphical path management tool from MATLAB. In this hands-on session we’ll manage the path from the command line, but in general you are much better off using a startup.m file than the path GUI.

Please do NOT add FieldTrip with all subdirectories, subdirectories will be added automatically when needed, but only when needed.

The restoredefaultpath command clears your path, keeping only the official MATLAB toolboxes. The addpath(pwd) statement adds the present working directory, i.e. the directory containing the fieldtrip main funcctions. The ft_defaults command ensures that all required subdirectories are added to the path.

If you get the error “can’t find the command ft_defaults” you should check the present working directory.
