I'm guessing your signals aren't actually the same length. If you're thresholding them independently, your thresh_start value won't be the same, so: onesec = x [thresh_start-1:one_sec] will give you different-length arrays for the two files. You can either calculate the threshold value separately and then provide that ... jeep 4g plus
