  1. Using SEED Using: Jrdseed PQL SAC RESP JPlotResp Data Management Workshop Kuala Lumpur, Malaysia

  2. Data Examples download • Create a download folder DATA_EXAMPLES • http://www.iris.edu/pub/userdata/Rick_Benson/WKSHOP • Get dataless SEED file MY.dataless • Get miniseed data file like KKM.MY..LHE.2007.276.R • Get file calledfullSEED Data Management Workshop Petaling Jaya, Malaysia

  3. Portable SEED File Reading Jrdseed - Java port of the IRIS-DMC’s ‘rdseed’ • Reads full SEED, dataless SEED and Mini-SEED+dataless • Writes SEED, SAC, AH, CSS, SEGY, SEED RESP • Time-window and other output selection possible • Runs anywhere a JVM is available • Based on generic JavaSeed classes available separately • Not as complete as ‘rdseed’ yet Data Management Workshop Petaling Jaya, Malaysia

  4. Jrdseed To install from Internet: • Connect with browser to: • http://www.iris.edu/manuals/rdseed_request.htm • Get Jrdseed or Rdseed depending on platform • Put in Applications folder. Data Management Workshop Kuala Lumpur, Malaysia

  5. Run Jrdseed • Two modes: command line or interactive Command Line, for scripting, etc Example: • Jrdseed -d -o 4 -f “seed_volume” • Will output a file called “mini.seed” in current working directory. (because we used -o 4) • NOTE: No alternate output filename supported, so if you run it iteratively, make sure you move the mini.seed file to a new name between iterations. Data Management Workshop Petaling Jaya, Malaysia

  6. Interactive Jrdseed Options for output: << IRIS SEED Reader, Release 4.7.5 >> Input File (/dev/nrst0) or 'Quit' to Exit: seed Output File (stdout) : Volume # [(1)-N] : Options [acCsSpRtde] : a: Abbreviation dictionary c: contents, timeseries C: Station/channel comments s: summary of entire volume S: station list into a file “rdseed.stations” p: Print SAC Pole/Zero files SAC_PZs_TA_U05C_BHN__2004.341.00.00.00.0000_99999.9999.24.60.60.99999 R: Print RESP format files t: Listing “timeseries” of waveform data in volume d: Output Format [(1=SAC), 2=AH, 3=CSS, 4=mini seed, 5=seed, 6=sac ascii, 7=SEGY] Data Management Workshop Petaling Jaya, Malaysia

  7. Jrdseed: conjoin w/ miniSEED and Dataless • By having separate miniseed and dataless, you can still run rdseed: • csh: setenv ALT_RESPONSE_FILE `pwd`/dataless • bash: export ALT_RESPONSE_FILE=`pwd`/dataless • Win: use the “-g” option • http://www.iris.edu/manuals/jrdseed.htm Data Management Workshop Petaling Jaya, Malaysia

  8. Jrdseed Exercise #1 • Run jrdseed and create RESP files with the “R” option. << Java SEED Reader, Release 0.07 >> Input File (/dev/nrst0) or 'Quit' to Exit: MY.dataless Output File (stdout) : Volume # [(1)-N] : Options [acCsSpRtde] : R Station List (ALL) : Channel List (ALL) : Network List (ALL) : Loc Ids (ALL ["--" for spaces]) : Input File (/dev/nrst0) or 'Quit' to Exit: quit Jrdseed completed. • We will be using these when running JPlotResp in just a bit Data Management Workshop Petaling Jaya, Malaysia

  9. Jrdseed exercise #2 • Run jrdseed and convert miniseed to SAC << Java SEED Reader, Release 0.07 >> Input File (/dev/nrst0) or 'Quit' to Exit: fullSEED Output File (stdout) : Volume # [(1)-N] : Options [acCsSpRtde] : d Station List (ALL) : Channel List (ALL) : Network List (ALL) : Loc Ids (ALL ["--" for spaces]) : Output Format [(1=SAC), 2=AH, 3=CSS, 4=mini seed, 5=seed, 6=sac ascii, 7=SEGY] : Select Data Type [(E=Everything), D=Data of Undetermined State, R=Raw waveform Data, Q=QC'd data] :E Start Time(s) YYYY,DDD,HH:MM:SS.FFFF : End Time(s) YYYY,DDD,HH:MM:SS.FFFF : Extract Responses [Y/(N)] : Writing IU.KIEV.00.BHE, 9267 samples (binary), starting 2005,196 08:34:39.3850 UT Writing IU.KIEV.00.BHN, 6372 samples (binary), starting 2005,196 08:37:58.1350 UT Writing IU.KIEV.00.BHZ, 7743 samples (binary), starting 2005,196 08:35:53.8350 UT Input File (/dev/nrst0) or 'Quit' to Exit: quit Jrdseed completed. • We will be using these to plot using SAC in a bit.

  10. SAC IRIS distributes and maintains support for SAC “Seismic Analysis Code” software developed by LLNL Stay informed, ask questions, and get help using user-group list: http://norman.iris.washington.edu/mailman/listinfo sac-help and sac-dev To access and install: http://www.iris.edu/manuals/sac Data Management Workshop Petaling Jaya, Malaysia
