WebEEGLAB is an interactive Matlab toolbox for processing continuous and event-related EEG, MEG and other electrophysiological data. The toolbox incorporates ICA, artifact … WebThe EEG data were filtered offline using equiripple filters between 1 – 95 Hz with a notch filter at 50 Hz (bandwidth 6 Hz) to remove mains interference. Channels were analyzed for artifacts (using either FASTER, SCADS, or supervised rejection), and any contaminated channels were interpolated. WebSelect the tutorial file “eeglab_data.set” located in the “sample_data” folder of EEGLAB. Then press Open. In theory, you should go through rejecting bad channels and bad portions of data before running ICA. However, the tutorial dataset is clean enough for running ICA without prior artifact rejection. jana sanderson mceachern wiki
