Processing steps for EEG

EEG data cannot be analysed directly. Several steps need to be taken to prepare the data for analysis. The subsequent steps are: 1. Remove line-noise (filtering) 2. Robustly reference the signal relative to an estimate of the “true” average reference. Click here to get more info on why we use the average signal as a reference (2b. Detect and interpolate bad channels relative to this reference) 3. Define trials / events in the data. Potentially via an additional output file from an experiment. 4. Identify noisy trials / events 5. Analyse the remaining data
