[webservices] Unreadable file format for miniseed data from web services

[Alessia Maggi]

Dear all,

Thank you very much for your rapid replies!

Doug : I have downloaded and tested your updated versions of qmerge / sdrsplit and qlib2, and they work just fine now.  Getting ms2sac to work just required recompiling it with the new qlib2 library, and was done in a matter of seconds.  Thank you very mmuch!

All my current automated routines for data analysis are based on the qug tools, but thank you to those who suggested using the seisFile package, I shall look into it.

Sincerely yours!
Alessia
