Hi,


My problem is this:
markptp command reads absolute value of maximum pick to pick.
Now I want to read only the largest peak or trough during the
waveform.I want to do it for ML magnitude.

Best regards,

Reza

    Dear Reza,

    I attached my macro for ML.
    the commets are in Turkish. But you can understand the computations.

    amplitudes are in nanometers. and WA magnification is 2800
    it search the three component for max. amplitude of WA seismogram between the lines 80 and 111 and write it to a file

    best regards
    onur
