Thread: Output envelope waveform in SAC

Hi,
I want to calculate and plot envelope waveforms in SAC. I am reading several waveforms recorded at multiple stations of a seismic network. I decimated the data using decimate function and saved them as separate SAC files. I read those decimated files and typed "envelope" in the SAC terminal. According to the SAC manual, envelope command computes the envelope function of the data in memory, but I don't understand how to save the output of envelope command as separate SAC files to plot later. I would much appreciate any suggestions.

Thanks
Abhash
