Thread: Re: miniSEED to SAC

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!

Geoff,
your answer could generate a misunderstanding for people not
familiar with miniSEED.
According to the definition of miniSEED and SAC files you cannot just
convert any miniSEED file into sac (the viceversa is always
possible indeed).
I assume that MacSac can read evenly spaced single channel streams
with no gaps.
Is not it?

Dear All -

MacSAC reads miniSEED directly. There is no reason why IRIS SAC
couldn't either, and eliminate the conversion steps outlined.

Hello Shahar,

Another option would be to use the mseed2sac converter, the source
code is available here:

http://www.iris.edu/pub/programs/converters/

mseed2sac will take a simple ASCII text file that contains the lat,
lon, elev and other simple metadata for the time series and insert
those values into the SAC headers during conversion. 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.

regards,
Chad

Hello, Shahar-

The easiest way to get fulllSEED from miniSED is to first get a
dataless SEED volume
(there are numerous network dataless volumes available online at
http://www.iris.edu/pub/RESPONSES/DATALESS_SEEDS/
and then use the program "rdseed"
http://www.iris.edu/forms/rdseed_request.htm

The manual for rdseed is online at http://www.iris.edu/manuals/rdseed.htm
and look for the "ENVIRONMENT VARIABLES" link at the top "Jump To:" section,
where you set the ALT_RESPONSE_FILE variable that enables you to read in
miniSEED, and output fullSEED.
Let me know if you need more help than this.
Regards,
Rick

Hi,

I received some raw data in miniSEED format.
How do I go from miniSEED to SEED? I have the station's location,
elevation and poles&zeros.
I tried to search online and in the SEED documentation, but
couldn't find an explanation on how to go from miniSEED to SEED or
how to create a dataless SEED for that purpose.

Thanks,

Shahar
