简介：
The following encoding formats are recognized: 1: ASCII 2: A 16-bit integer representation. 3: A 24-bit integer format, currently unverified. 4: A 32-bit integer format. 5: IEEE float32 data. 6: IEEE float64 data. 7: Steim-1 encoding. 8: Steim-2 encoding. 9: GEOSCOPE 24-bit data, which remains unverified at this time. 10: GEOSCOPE 16/3-bit gain ranged data. 11: GEOSCOPE 16/4-bit gain ranged data, currently unverified. 12: Steim-3 encoding (incorporating both alpha and untested versions). For exporting data in the miniSEED format, consult the MKMSEED tool.

Acknowledgments are extended to Ljupco Jordanovski, Jean-Marie Saurel, Mohamed Boubacar, and Jonathan Berger, as well as Shahid Ullah for their contributions. Relevant references include the IRIS (2010) SEED Reference Manual (Version 2.4), published by IFDSN/IRIS/USGS and accessible via http://www.iris.edu; and Trabant C.s (2010) libmseed – the Mini-SEED library, available through the IRIS DMC. Additionally, Steim J.M.s (1994) work on Steim Compression from Quanterra Inc., is a valuable reference point for understanding this compression method.. Historical development notes indicate the following updates and corrections: [2012-04-21] – Resolved a bug related to Steim compression combined with little-endian coding; this correction was made possible thanks to Shahid Ullahs assistance.. [2012-03-21] – Introduced identification codes for warning messages to enhance debugging capabilities.. [2011-11-10] – Corrected a bug concerning multiple channel name lengths; Jonathan Berger’s input proved invaluable in resolving this issue.. [2011-10-27] – Incorporated a LocationIdentifier field within the X.ChannelFullName attribute.. [2011-10-24] – Implemented validation procedures specifically designed for IEEE double encoding, utilizing PQL for verification purposes.. Furthermore, the ability to import and plot data even when file integrity issues are present—such as those encountered with PQL—has been added.. [2011-07-21] – Validated the ASCII encoding format through logging mechanisms.. Blockettes are now organized within substructures situated below a single field designated as X.BLOCKETTES.. The import of blockettes identified as 500 and 2000 has also been implemented.. The system now supports processing multi channel files that utilize various different data coding schemes.. [2010-10-16] – Developed an alpha version of Steim decoding for Steim -3... Extended output parameters to include channel detection functionality; additionally gaps and overlaps have been incorporated into plotting capabilities; furthermore there is now an option to force plot generation.. [2010-10-02] – Added support for input formats used in GEOSCOPE multiplexed old data files... An additional output argument has been introduced that provides detailed analysis of gaps and overlaps... The script has also undergone optimization resulting in a significant speed improvement—specifically a reduction in STEIM decoding time by approximately thirty times!. [2010–09–28] - Resolved an issue pertaining to STEIM– 3 nibble decoding where a discrepancy of one % 3 -bit difference existed due to endianness issues; additionally reading files without blockette number          ¹⁰⁰⁰ has been enabled using additional input arguments similar to those used by Seismic Handler output files; finally replaced fprintf() calls with warning() function calls.
