[CIG-SEISMO] Help with visualizing output in Google Earth

Thu Jun 3 20:12:06 PDT 2010

Thanks Daniel for the quick reply.

As per your instructions, I checked the temporary **.ps and **.png files 
and only the postscript files have waveforms. The temporary png files 
were just blank images. I'm attaching the log of the output when I 
issued the script. I suspect that the error is in the cropping of the 
postscript file but I'm not really sure though.

Thanks again,

Nena
