Getting started with the hands-on sessions
For the hands-on sessions you have to start MATLAB. Make sure you have downloaded the hands-on data prior to the start of the workshop as it is quite a large download. A recent version of FieldTrip can be downloaded here, and the tutorial data can be downloaded here.
Depending on the unzip program you are using (e.g., Winrar), the name of the zip file might also appear as directory, 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 weβll 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 functions. The ft_defaults
command ensures that all required
subdirectories are added to the path.
If you get the error βcanβt find the command ft_defaultsβ you should check the present working directory.
After installing FieldTrip to your path, you change into the data directory
cd path_to_directory/data
