  • For each file (myfile1.p and myfile2.p), the above example computes the average of channels 1 and 2, the average of all channels and creates a file with 2 channels (one for each average).
    It creates myfile1.avgelec.p (average of myfile1.p channels) and myfile2.avgelec.p (average of myfile2.p channels).
