I see that your file can be treated as csv format, therefore you could use numpy.genfromtxt ('file.csv', delimiter=',') function. Use the scipy function for median filtering: scipy.signal.medfilt (data, window_len). Keep in mind that window length must be odd number. Save the results to a file. trailer belle und sebastian 2023
