This is a SeedLink plugin that collects data from an Earthworm export_? process. Usually the export_scn program is run on a host with access to the appropriate data; export_scn is a version of export_generic that will only transfer waveform data. While ewexport_plugin will accept any Earthworm messages only waveform data will be processed. Only waveform data in TRACEBUF packets will be processed, the plugin does not support the newer TRACEBUF2 packets.

The IRIS-WS Library is a Java API that allows direct access to data and information at the DMC from within your programs. This library constructs the service calls based on criteria you define, and accesses the web services behind the scenes. Information is retrieved as Java objects that are available for immediate manipulation, bypassing the traditional “save to disk, reload into my program, and then parse the data format” series of steps.

This Library allows a Java developer to access DMC-stored data without dealing directly with the web service interfaces or, more importantly, the internal formats of the DMC. Even though the web services typically return XML or SEED data, users of this library do not need XML or SEED knowledge to process the returned information.

This is a SeedLink plugin to grab data from an Antelope ORB. The plugin packages any selected data streams coming into the Antelope ring buffer as 512-byte big-endian miniSEED records and sends them to the controlling SeedLink daemon. No “re-ordering” of data is performed, it is assumed that data comes into the ORB sequentially. This may cause unexpected behavior with data streams allowing out-of-order transmission/reception such as CD-1, likely resulting in many unfilled miniSEED records.

The purpose of Portable Data Collection Center (PDCC) is to enable seismic network operators to describe and maintain their instrument metadata in SEED format. Version 3.8 introduces an updated Station Clone Tool that allows the user to create new stations and modify critical differentiating fields in a simple tabular entry form. Blockettes are also represented in a more human-readable form. Other minor enhancements are also included.


This current Patch Level 1 release is a patch release to address an issue with launching PDCC using newer patch releases of the Oracle Java JVM. The functionality is identical otherwise. More details can be found in the Revision History tab.

Known Issues: rdseed 5.3.1 is the current release and has four primary issues that IRIS DMC staff are looking into.

  1. compatibility issues with summary files produced by JWEED 4.1 (Linux)
  2. segmentation faulting when attempting to produce SAC files with user-compiled code coupled with a JWEED summary file
  3. user difficulty building rdseed from source using the latest gcc (Linux, Mac)
  4. gain of CSS output for infrasound channels off by 10^9

IRIS currently has limited resources to support rdseed and response time regarding rdseed issues may be longer than normal. Nonetheless, we are endeavoring to put out new releases to address these reported problems. Thank you for your patience.

rdseed is IRIS DMC’s legacy utility for reading SEED volumes, the FDSN-approved file format for representing and distributing digital seismic data. This utility allows the user to read the contents of the SEED file and convert it to many different output formats, extracting the data, station information, or instrument responses from the file.

The IRIS DMC distributes the Seismic Analysis Code (SAC) software for scientists conducting research using IRIS data. You must register with an online form to receive the SAC software.

SAC Version 101.6 introduced several new features including a new command parser that simplifies coding, improved precision for blackboard variables, colored fill for positive and negative portions of seismograms, and corrections of many errors and warnings.

Version 101.6a fixes bugs in v101.6 and adds a single-file PDF version of the SAC manual. Details can be seen from the detailed HISTORY of modifications files and brief overview of major CHANGES posted in the SAC project pages on SeisCode.

The TauP Toolkit is a seismic travel time calculator. In addition to travel times, it can calculate derivative information such as ray paths through the earth, pierce and turning points. It handles many types of velocity models and can calculate times for virtually any seismic phase with a phase parser. It is written in Java so it should run on any Java enabled platform. Unfortunately, gjc, which comes with many Linux distributions, is not quite Java and prevents TauP from finding its model files. Please use Java from Sun on Linux instead.

1 – If more than one version is listed it means that a specific set of functionality was added or removed and legacy versions that preserve behaviors are archived.

2 – Development group(s) responsible. If IRIS and another group is listed, this usually means IRIS funded an external group for development.
