eeg = import_edf("files/eeg_edfplus.edf");Epoching is a procedure in which specific time-windows are extracted from the continuous EEG signal; these time windows are called epochs. Epochs usually are time-locked with respect an event e.g. a visual stimulus. Recorded data is stored as matrix channel × time (where time is the complete continuous the signal). After the epoching procedure the matrix is transformed into an array: channel × time × epochs, where time is the time length of each epoch, and epochs is the number of segments you extracted from continuous signal.
Imagine we have a signal with length of 60 s and our sampling frequency is 1 Hz. The matrix representation of your EEG signal would be 1×60 array or matrix, so if you divide your main signal to some 2 s signals, you would have 30 epoch (each 2 s of your main signal would be an epoch). This could be done by a simple for loop resulting in a new matrix which size is 30×1×2.
If you want to extract epochs from your signal, you should know what are the segments of interest to be analyzed, for instance, a specific stimulus.
(!) Many processing operations (such as filtering or ICA decomposition) should be performed on non-epoched (continuous) signal (e.g. due to the edge artifacts that may occur in case of filtering or the minimum required signal length for ICA decomposition).
Create epochs
Split EEG into 10-second epochs:
