Import Data


This step imports EEGLAB .SET data and saves them as .MAT files. Here, EEG trials can also be smoothed across trials using a moving window average. This is useful to further denoise the data when one predominantly wants to look at slower dynamics across trials. Smoothing does not dramatically alter the outcome of the group ICA. When you click on Import Data button, a figure (Figure 1) will open to select the EEG files in a data format that EEGLAB toolbox uses. After selecting the data files, an input dialog box will open (Figure 2) to enter the following parameters.
