Before installing EEGIFT you need to unzip 'eeg_example_subjects.zip' file. This file contains three subjects from oddball task in .SET format (Format used by EEGLAB). The dimensions of the data are 512 time points by 400 trials by 64 electrodes. Also contained in the zip file is the EEG channel locations file from EEGLAB ('oddball_locs.locs') which will be used during display of group ICA components. More information on the task is given in Appendix A .
Download 'GroupICATv4.0a.zip' file and unzip into an appropriate directory. Add icatb and its sub-folders to MATLAB search path. You can also add path when you run 'groupica.m' or 'eegift.m' file and this will automatically add folders and sub-folders at the bottom of the MATLAB path to fix the menu problem for figures. You can open EEGIFT toolbox (Figure 2) in two ways when you click on EEG button (Figure 1) or enter groupica 'eeg'.
