Hi every one, Sac reads the max peak point during the waveform and save them in Depmax or Depmin. I want to read Depmax or Depmin in a specific place. For instance in S group or around T0. Markptp can read in a specific window but it reads peak to peak and I want to read only peak in a window range. I would be pleased if you help me. Thank you, Reza,
