+==== Extracting data from a gzipped tar archive ====
+As SEED volumes are no longer supported, waveforms and instrument response can also be retrived from a gzipped tar archive (hereafter referred to as "tgz") including SAC and SAC_PZ (poles and zeros) files. Instead of using the "extract.csh" script to extract data from SEED, we can then extract data from a tgz archive using:
+<code>${WPHASE_HOME}/bin/tgz2DATA_org.py path_to_tgz_archive.tgz</code>
+where "path_to_tgz_archive.tgz" is the path to the tgz archive including SAC and SAC_PZ files.
+Two tgz archive formats are supported: WILBER (default) and NIED.
+Using the WILBER format, SAC files should be named with a ".SAC" or ".sac" extension and SAC_PZ file names should start with "SAC_PZ". Although this is the default format, extraction from a WILBER archive can be stated explicitly by running
+<code>${WPHASE_HOME}/bin/tgz2DATA_org.py path_to_tgz_archive.tgz wilber</code>
+Using the NIED tgz archive format, SAC_PZ files should end with ".zp" and SAC file names can have any format (but should not end with ".zp"). Extraction from a NIED archive can be done using
+<code>${WPHASE_HOME}/bin/tgz2DATA_org.py path_to_tgz_archive.tgz nied</code>
