This means that the original data is individual digital event waveform files generated
by some data acquisition system. The waveform data can be stored in SEISAN, MiniSeed, GSE
and SAC format as single or multi trace files. The files that are used in conjunction
with the database are normally stored in WAV but can also be in the user's directory,
e.g. WOR. The normal scenario would be that multiplexed files
would be transferred from a digital field station, demultiplexed and converted to
SEISAN or other waveform format, preferably MiniSeed. Programs are provided to convert from most of the popular
waveform formats like MINISEED, GSE
and from commercial recorders. It is most practical to initially put the files in WOR, check the events for false triggers, save the true events in WAV, make the corresponding S-file and a hardcopy of the digital data.
All of this can be done with the program MULPLT. The program plots channels from a single waveform file. The user can then interactively decide if this is an event to keep, in which case an S-file is created in the database and the event is moved to WAV.
Alternatively, all new waveform files can be auto-registered into the database (AUTOREG) and all checking takes place from EEV or SE.
When digital data is the input to the analysis system, MULPLT is the program to use to get data into the database. From there on further analysis can be done with EEV (picking phases, locating and editing). MULPLT is also the program used with EEV. For more details on MULPLT, see detailed description in section 8.
Metadata: SEED or dataless SEED
See also chapter 2.2.3.
To get SEED or dataless SEED metadata into a SEISAN database, you need the RDSEED program from GitHub.
SEISAN include an old version of RDSEED, find the newest at:
https://github.com/iris-edu-legacy/rdseed
See also End of Life Notice from IRIS:
https://ds.iris.edu/ds/nodes/dmc/software/downloads/rdseed/
First you need to extract the Staion information from the SEED or dataless SEED file, use the command:
rdseed -S -f <file>
Then you need to extract the response information from the SEED or dataless SEED file, use the command:
rdseed -R -f <file>
Now you must list the response file, use the command:
dirf RESP.*
Then you run the program RDSEED2SEISAN, this program give a output file rdseed.STATION0.HYP with station coordiantes that you can add to your STATION0.HYP file in the DAT folder. And it gives a output file rdseed.SEISAN.DEF with ARC_CHAN lines that can be added to you SEISAN.DEF file in DAT, if you wish to store the data in an archive (e.g. BUD or SCP).
Finally you must move the RESP file to the CAL folder.
Waveform data: SEED or miniseed data
To get SEED or miniseed waveform data into a SEISAN database, you need the RDSEED program from IRIS (see URL above).
And the DATASELECT program from IRIS if you wish to use an archive for the data:
https://seiscode.iris.washington.edu/
First you need to extract the miniseed data from the SEED, use the command:
rdseed -o 4 -f <file>
Then you need to send the data to the archive defined in the SEISAN.DEF file.
This is done using the program DATASELECT that you need to download from:
https://seiscode.iris.washington.edu/projects/dataselect/wiki
An older version of DATASELECT is found in the SUB folder.
For a SeiscomP archive, use the command for waveform data:
dataselect -A archive-path/%Y/%n/%s/%c.D/%n.%s.%l.%c.D.%Y.%j mini.seed
For other types of data use:
E:Detection data, L:Log data, T:Timing data, C:Calibration data, R:Response data, O:Opaque data.
See http://www.seiscomp3.org/doc/jakarta/current/apps/slarchive.html.
For a BUD archive, use the command:
dataselect -BUD archive-path mini.seed
Where archive-path must be the same path as ARC_ARCHIVE
that is defined in SEISAN.DAT.
To plot the archived waveform data use the command textttarc in eev, before you call MULPLT
