Support for another Q files? #86

Open ihuangz opened 2 years ago

ihuangz commented 2 years ago

Hi Jones,

have you planned to support the Q files of Seismic Handler?

Another issue, is it possible to read the data directly from the .tar/tar.gz/tar.bz2 files?

Regards,

Zhouchuan

I'm mostly unfamiliar with Seismic Handler, but everything I've found about it suggests that it uses mini-SEED. There's mention of a "Q format" in https://www.seismic-handler.org/chrome/site/sh.pdf, but that particular PDF was last updated 27 April 1992 and I'm not seeing any description of the Q file format. Could you please provide a link to the file format spec?

Perhaps you may find it in the Obspy module:
