Instead of using the "extract.csh" script to extract data from SEED, we can then extract data from a tgz archive using: |

| - | Two tgz archive formats are currently supported: namely WILBER (default) and NIED. Using the default WILBER (i.e. IRIS) format, SAC files should be named with a ".SAC" or ".sac" extension and SAC_PZ file names should start with "SAC_PZ".
