[SAC-HELP] miniSEED to SAC

[George Helffrich]

Dear Marco -

	In the context of this query and discussion, there's no possibility of any additional confusion that you imply.

	MacSAC will read miniSEED.  If the data contains gaps or overlaps, you'll be warned.  You can change header information to add any additional station information you need, which the user said was available.

PS - I am assuming your response is directed to me, even if my name isn't Geoff!

This format of the text file is documented in the man page included with the source code.  There is also an option to insert values into the SAC event headers during conversion if you want that information included.
