Planned Data Services Website Outage


At 10:00am PDT (UTC-7) on 2017-04-27 there will be some maintenance being performed on the IRIS DMC database. This maintenance period is expected to last approximately 10-20 minutes.

During this time, parts of the IRIS DS website may be down and unresponsive.

Manuals: Jrdseed


Jrdseed – A Java port of our classic rdseed application developed by ISTI.


A Java version of rdseed currently under development. This evaluation supports core rdseed functionality, including the reading and writing of SEED volumes, as well as SAC (binary) and CSS output. SAC ASCII format is forthcoming. SEGY output is not being considered in the short term.

Treat the operation of Jrdseed much like you would the legacy rdseed code. As for the command interface, some features are not being used in the current release:

  • In place of ALT_RESPONSE_FILE, use the -g flag on the command line to indicate a dataless SEED file to use for response information.
  • The volume number (-v) option: SEED files with multiple volume numbers are no longer used.
  • The start/stop times (-t) output will not have the logical record sequence number printed.
  • The list contents of each record in the volume (-l) option is not supported.
  • SAC ASCII output is not in SAC format, but is a currently a rudimentary delimited ASCII output.
  • SAC poles and zeroes output is not supported.
  • SEGY output is not supported.

For those not familiar with the rdseed interface, please refer to the rdseed online manual

The rdseed manual will tell you how to use Jrdseed, aside from the feature differences mentioned above. The other critical difference is how you start Jrdseed. Since it uses Java, you have to use the Java launcher on the .jar file itself (Java 1.5 or later is required):

java -jar JrdseedVer0.10.1.jar

How do I run Jrdseed?

Jrdseed must be run from the command line.

In Windows

Go to Start-->Run...
Type 'cmd' in the prompt. You should get a terminal window.

Other Operating Systems

For other operating systems, use a Terminal window.

cd 'your_Jrdseed_directory' (substitute with your directory for Jrdseed)


java -Xmx512m -jar JrdseedVer0.10.1.jar

for a 512 MB memory allocation, or:

java -Xmx1024m -jar JrdseedVer0.10.1.jar

for a 1 GB memory allocation.

A sample session with Jrdseed looks like:
