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 called fullSEED

Portable SEED File Reading
Jrdseed - Java port of the IRIS-DMC’s ‘rdseed’
• Reads full SEED, dataless SEED and MiniSEED+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

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.

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]

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
