This file contains a high-level, user relevant description of the GIPPtools evolution back to 2008. The list is sorted in reverse chronological order (i.e. most recent GIPPtools release first).
Releases are named after the date of their release. The first number indicates the release year, and the three-digit number after the dot is the respective day-of-year number of the software release date. |
Release 2021.168
-
CHG The GIPPtools now expect at least a working Java virtual machine (sometimes also called a Java Runtime Environment or simply JRE) supporting Java 8 or newer!
This change became necessary as it becomes increasingly difficult to generate Java class/jar files on up-to-date platforms that are still backward compatible back to Java Release 5! -
UPG Improving the check for corrupted Cube files. The algorithm originally used when this check was introduced with the previous GIPPtools release produced to many false alarms when the GNSS reception is not optimal.
-
UPG Support Cube logger with build-in u-Blox GNSS receiver board as time source.
-
UPG Updated the leap seconds list based on Bulletin C number 61 (published by the Earth Orientation Center of IERS). The new leap second list will expire December 28th, 2021.
Release 2020.352
-
FIX Cube conversion tools will ensure that the time between consecutive Cube time tags "flows" in the right direction.
This additional check was inspired by a corrupted Cube file read from a failing drive. It somehow contained fragments of an earlier recording and converting the data to miniSEED resulted in misleading error messages and other "surprising" results. -
FIX The
--include-pattern=GIPP
filename filter now accepts month numbers larger than '12'!
There is a new option in the Cube firmware that forces a strict increment of the month number for each consecutive month. If used in a recording that starts in December then January would become '13', February would be '14', and so on. The option is intended for long-running (> 1 year) continuous recordings where otherwise filenames might repeat. (Cube filenames do not include a year.) Obviously, Cube filenames beginning with such higher month numbers should nevertheless be included by the GIPP filename filter, hence the change. -
FIX Corrected the handling of Cube "system event" block containing more than two bytes. Previously,
cubeinfo
would stop working when encountering one of those rare blocks. (This bug did not affect other Cube related utilities.) -
UPG Automatically add a blockette #1001 to the miniSEED record if necessary. A blockette #1001 adds (among other things) microsecond resolution to the start time of the miniSEED record. This will improve the timing precision in situations where the miniSEED output requires more resolution after processing
An example would be a 300 Hz recoding, where some recording times contain repeating decimal numbers (e.g. 14:20:09.953333…; with an infinite number of "threes" in the fractional second part). -
UPG Updated the leap seconds list based on Bulletin C number 60 (published by the Earth Orientation Center of IERS). The new leap second list will expire June 28th, 2021.

Lendl, Christof (2020), GIPPtools, Version 2020.352, doi:10.5281/zenodo.4707612.
Release 2020.161
-
FIX The
mseed2segy
utility no longer crashes when the miniSEED input is fragmented and contains gaps/overlaps. This only happened under very scarce circumstances. -
UPG Updated the leap seconds list based on Bulletin C number 59 (published by the Earth Orientation Center of IERS). The new leap second list will expire December 28th, 2020.
Release 2019.332
-
NEW Added a
--bugfix-gps-epoch
command line option to themseed2mseed
utility. It is intended to be used to fix incorrect recording times that were caused by a GPS week number rollover (WNRO) problems. Please see the program documentation for more details on how to apply the corrections. -
UPG Updated the leap seconds list based on Bulletin C number 58 (published by the Earth Orientation Center of IERS). The new leap second list will expire June 28th, 2020.
Release 2019.155
-
FIX The miniSEED utilities stumbled over partially read blockettes. The problem surfaced for the first time when the mandatory blockette #1000 is placed after an optional blockette #100 (i.e. parts of blockette #1000 extend beyond the initially read 64 byte).
-
NEW Added (preliminary) read support of blockette #100 ("sample rate"). If a miniSEED record contains a blockette #100, the sample rate information from the blockette will supersede the sample rate information from the fixed header area.
-
UPG Improved I/O speed when converting Cube data to miniSEED/ASCII.
-
UPG Updated the leap seconds list based on Bulletin C number 57 (published by the Earth Orientation Center of IERS). The new leap second list will expire December 28th, 2019.
Release 2018.310
-
FIX Detect corrupted Cube files containing very large blobs (i.e. >8 MB) of "zero" bytes. The GIPPtools will attempt to convert as much data as possible up to the location of the first corrupt area in the file and then skip ahead to the next input file.
-
FIX Detect Cube file corruption resulting from a sample block containing a few bytes to many. (Previously, only the more common case of a few missing bytes in a Cube sample block was detected reliably.)
-
FIX GIPPtools incorrectly assumed that blockette #1000 is always the first blockette following the fixed header section of a miniSEED record.
-
FIX Huge time spans are now parsed correctly. This affected e.g. the
--shift-time
option of themseed2mseed
command when shifting the start time of a miniSEED record by more than 68.1 years. (Cause of the problem was an undetected integer overflow.) -
FIX Changed the Microsoft Windows start scripts to correctly set the
ERRORLEVEL
return code variable after the execution of a GIPPtools utility. -
UPG Updated the leap seconds list based on Bulletin C number 56 (published by the Earth Orientation Center of IERS). The new leap second list will expire June 28th, 2019.
Release 2018.155
-
FIX Corrected a bug in the Windows start scripts that caused the utilities not to start at all if the path to the GIPPtools installation directory contained spaces or other "problematic" characters.
-
UPG Improved error message when the Cube header block contains illegal (non-ASCII) characters like German "umlaute" or French accents. (Note: Non-ASCII characters are still illegal in the Cube header!)
-
UPG Updated the leap seconds list based on Bulletin C number 55 (published by the Earth Orientation Center of IERS). The new leap second list will expire Dec 28th, 2018.
Release 2017.340
-
FIX Corrected an obscure "array index out of bounds" error in the date/time computations. The code parsing the GPS time information did not correctly handle the situation of a leap second event being recorded on Dec 31st of any year (opposed to events occurring on Jun 30th, which worked flawless). This error only shows if the Cube GPS unit is actually powered on during the leap second event.
-
FIX The
mseed2pdas
utility now correctly identifies miniSEED files recorded by an EDR-209/210 units. -
OPT Reduced the memory consumption (RAM) of the cube2ascii and cube2mseed utilities by roughly 30% at the price of a slightly increasing runtime by about 3%.
-
UPG Added detection of duplicate miniSEED records when rescuing data from corrupted media with the
mseedrecover
utility. This is the new default behaviour but can be switched off using the--no-dedupe
command line option. -
UPG Added a new timing "quality control" algorithm (
--timing-control=FAKE
) to the utilitiescube2ascii
,cube2mseed
andcube2segy
that replaces all Cube timing information by a made-up "fake time".Only use this algorithm for worst case scenarios, where a user ends up with a Cube data stream that cannot be processed due to total lack of (recorded) timing information! By adding fake time information to the Cube file becomes processable again, although at the price of a completely made-up time information.
Please see the documentation for details before using it. -
UPG Add a command line option to fix certain faulty record start times encountered in miniSEED files that were recorded by an EDR-209/210 data logger running a specific, buggy firmware. Please see the
mseed2mseed
manual page for details. -
NEW Added support for the new (and still experimental) event recorder units designed to record the trigger time of seismic sources. Specifically, the new utility
cubeevent
can be used to read detected/recorded events from files. In addition, the other Cube related GIPPtools (cubeinfo
,cube2ascii
, etc.) were upgraded as well to correctly handle event recorder files. (This works because event recorder write a variant of the Cube file format.) -
NEW Added a
config
subdirectory to the GIPPtools distribution. At the moment it only contains a copy of the latestleap-seconds.list
file. In the future it will also contain things such as default settings or user preferences.
Release 2017.013
-
CHG Added an expiration date to the internal leap second table so that GIPPtool utilities will not accidentally apply outdated leap second corrections. As a consequence, the Cube conversion tools (
cube2ascii
,cube2mseed
andcube2segy
) will refuse to process a file if the available leap second information is outdated (with respect to the Cube input). Thecubeinfo
program will output a warning. Utilities processing miniSEED formatted (input) data are not affected. -
NEW Added a
--sysinfo
command line argument to all GIPPtool utilities. Using it will generate a brief report of the (GIPPtools relevant) computing setup you are using. The system summary should be helpful for diagnosing configuration problems or when reporting bugs to the developer.
Release 2016.358
-
FIX The
mseedrecover
utility will (again) read directly from a Unix/Linux device file. (There was an overeager safety check that complained about a device file of "zero length".) -
FIX Implemented a workaround for the "Could not parse TAIP message…" error message. This bug only affected users that (still) use an outdated Java 1.6 runtime to convert files recorded by Cubes with build-in "newer" GPS board. This bug did not surface when using Java 1.7 or newer.
-
FIX Added a proper error message when reading from miniSEED files that contain an uninitialized "record size" header field (i.e. claim an impossible miniSEED record size of zero).
-
FIX Corrected a faulty range check when writing miniSEED files using IEEE single precision floating-point encoding.
-
FIX Repaired the
--record-size
command line option of thecube2mseed
utility, which was not accepting any number at all. Cause was an internal integer overflow when comparing the given record size with a build-in, upper limit. -
UPG Updated internal leap second table with the upcoming leap second event on 2016-12-31.
-
UPG Upgraded the checksum calculation (option
--format=CHECKSUM
) of themseedinfo
utility to use the MD5 algorithm provided by the Java runtime. If accessing the MD5 algorithm fails for some reason, it will automatically fall back to SHA-1 or the previously used CRC-64 algorithm. -
UPG Added a
--shift-time
command line option to themseed2mseed
utility that will move the start time of miniSEED records by the given time span. -
OPT Updated the
cube2segy
utility to use the same Cube I/O subroutines ascube2ascii
andcube2mseed
. Due to the (internal) change the utility will be more resilient to bad GPS reception. This should also improve timing precision on sub-sample level. -
CHG The Cube conversion tools (
cube2ascii
,cube2mseed
andcube2segy
) contain a new (default) algorithm to better quality control the recorded timing information (option--timing-control=LLS
).
The main advantage of the LLS algorithm is its flexibility. It was designed to adapt to different situations and to handle different time keeping hardware as well. However, you can use the command line option--timing-control=RULE
to fall back to the previously used timing quality control method. -
CHG Slightly modified the GPS output format (
--format=GPS
) of thecubeinfo
utility. The reported leap second information now clearly indicates the origin of that information. The string gps-leap stands for leap second information obtained from the GPS satellite broadcasts, while iers-leap indicates leap seconds as officially announced by the International Earth Rotation and Reference Systems Service (IERS). The later are kept in an internal table. -
CHG Renamed the
DUMP
output format of thecubeinfo
utility toDEBUG
, which more clearly indicates its intended use.
Release 2015.225
-
FIX Handle the case of a misspelled input file or directory more gracefully (i.e. with a proper warning message instead of just skipping the non-existing file silently).
-
FIX The
mseed2mseed
utility erroneously did not correctly re-encode an input file containing more than 64 miniSEED records. Everything worked fine for the first 63 records, however, the following 63 records were not re-encoding at all. (No data was lost, but the output files contained the later records in their original miniSEED encoding!) And yes, this is a follow-up to the (apparently incomplete) bug fixed in the previous release. Sorry!
Release 2015.196
-
FIX The
mseed2mseed
utility erroneously produced data gaps in the output when an input file containing more than 64 miniSEED records.
This only happened while re-encoding the data (using at least one of the options--record-size
,--encoding
and--byte-order
). Basically, an internal buffer was not flushed (completely) when the end of an input file was reached, resulting in missing data in the output. -
FIX Handle the case of a zero length input file more gracefully, (i.e. with a proper warning message instead of a null pointer exception).
Release 2015.166
-
FIX Something went wrong while packaging the previous 2015.163 release. Unfortunately, Java classes were compiled without the correct backward compatible setting. The resulting GIPPtools release required at least a Java 1.7 runtime. A quick re-compilation with correct settings solved the problem.
Release 2015.166 is functional identical to 2015.163 with the single exception that it requires only a Java 1.5 runtime environment!
Release 2015.163
-
NEW There is a new
cube2ascii
utility that works just like the already existingcube2mseed
but outputs the Cube trace in ASCII text format instead of miniSEED format. -
UPG The
cube2mseed
utility was completely rewritten from scratch! The new version will correctly handle Cube data streams spanning over several files, long(er) periods without GPS reception and compensate for drifting clocks by resampling the Cube input. -
CHG Due to some internal changes, the checksum calculation for miniSEED files (command
mseedinfo
--format=CHECKSUM
) had to be changed.
Do not compare checksum calculated by an earlier GIPPtools release with checksums calculated with themseedinfo
tool of this (and future) releases! All checksum must be re-calculated! -
NEW Added IEEE double (
--encoding=FLOAT-64
) and single (--encoding=FLOAT-32
) precision floating-point numbers to the supported miniSEED encodings! -
FIX Took care of a problem, where creating files of equal length (e.g. when running
mseedcut
--file-length=DAY
) would occasionally "forget" a single sample value in the data stream. This error occurred only when a very specific combination of sample amplitudes and miniSEED record layout was encountered, which is probably the reason it went undetected for such a long time. -
FIX Took care of another problem while creating files of equal length (e.g. when running
mseedcut
--file-length=DAY
). Once in a while a file of twice the desired length would be generated instead of two separate files. This error happened when the first sample of a new file was also located at the end of a miniSEED record in the input. Chances for this to happen depend on the used miniSEED encoding but are typically in the range from 1:1000 to 1:2000. -
FIX Utility
mseedcut
now correctly handles event files (option--events=file
) as exclusive source for user requested time windows. Before, it would only process an event file when an additional time window was requested via other command line parameters. -
FIX All Cube related utilities now correctly handle the error case of two time tags following directly after each other in the recorded data stream. (Expected is approximately one second of samples in between time tags!)
-
FIX Due to a firmware bug in (some) Trimble GPS boards, affected Cube recorder erroneously compensate a future leap second the moment it is announced via satellite and not starting at the time when the new leap second will happen. Unfortunately, pending (new) leap seconds are usually announce via GPS satellite many weeks in advance of the actual change… A workaround was added to the GIPPtools to compensate for the premature leap second correction.
-
FIX Removed a bug, where an uninitialized internal variable accidentally would prevent the display of an error message.
-
UPG Updated all Cube related GIPPtools so that they can handle the recent additions to the Cube data format. Especially the
cubeinfo
program now reports on auxiliary channels as well as event and debug blocks when called with option--format=SUMMARY
or--format=DUMP
.
Release 2013.268
-
FIX Took care of a stupid decoding error when reading Steim compressed miniSEED files written by the new EDR-209/210 logger from EarthData.
-
UPG Added a new output format called QUALITY to
mseedinfo
that provides information about the data quality flag and (if available) the timing quality value stored in a miniSEED record. The same information was also added to the HEADER output format ofmseed2ascii
. -
UPG Updated the
cubeinfo
tool, so it knows about the newest enhancements to the Cube hard- and software (such as e.g. auxiliary recording channels, and the new GPS board). -
FIX Ignore GPS information read from Cube files when the latest corresponding GPS fix is older than 10 seconds. (Note: This patch is only relevant for Cube recorders with the new GPS board actually providing that information. Cube files written by recorders with first generation GPS boards cannot provide the necessary GPS information in the first place. No need to reprocess old files!)
-
UPG Expanded the GPS output format of the
cubeinfo
tool (command line option--format=GPS
) to give an idea about the GPS reception and the quality of the Cube time information. Additional values (elevation and temperature) become available when the used Cube recorder contains one of the new GPS boards providing that information. -
NEW Added a new environment variable
GIPPTOOLS_OPTS
that can be used to fine-tune the Java runtime. This would typically be used to set the Java heap size available to GIPPtool programs. -
FIX Made
cubeinfo
more resilient to crashes when working with damaged or incomplete Cube data files. -
NEW Finally got around to write a proper
Readme
file and to start a Frequently Asked Questions (FAQ) list.
Release 2012.093
-
FIX Took care of a problem where
mseedcut
failed to produce files of equal length (option--file-length
) if no sample was recorded precisely on the hour. This became a problem when working with converted files that were originally recorded by a Cube.
Release 2012.088
-
UPG
Mseed2mseed
now understands the keyword RESET when parsing actions in a rule file or at the command line. Use the new keyword to clear/remove id values in miniSEED header fields. -
NEW The utilities
cube2segy
andmseed2segy
can now cache the (internal) file index that is build from the input files. Using the new--index-cache
option is especially helpful If you plan to use one of the programs repeatedly on the same, large dataset. -
UPG Improved syntax checking of the project file (utilities
cube2segy
andmseed2segy
) enables better user feedback (i.e. error messages) when the format of the project file is almost but not quite correct. Also added a few integrity checks to catch obvious typing errors.
Release 2011.321
-
CHG Renamed EDL/miniSEED related GIPPtools by replacing the string edl with mseed in the respective command name:
-
edl2ascii
→mseedinfo
(to inspect files) +mseed2ascii
(for conversion) -
edl2edl
→mseed2mseed
-
edl2pdas
→mseed2pdas
-
edlcut
→mseedcut
-
edlrecover
→mseedrecover
-
edlrename
→mseedrename
-
-
UPG The
mseedrename
utility will now try to preserve the "last modified" time of a file while renaming it. -
UPG Added an
--events
option to themseedcut
utility. Use this option to cut out more than one time window during a single program run. -
FIX Added an extra test to
mseedrecover
to make sure that all samples (and not only the header fields) of a recovered miniSEED record are readable as well. Before this bug fix, some only slightly damaged records were not detected reliably. -
CHG The change introduced to the
cube2segy
andmseed2segy
utility in the last 2011.166 release was reverted after user protest. By default, both tools behave again as accustomed when writing seismic sections, creating a separate file for every shot/receiver gather requested.
Use the new command line option--force-concat
when all resulting seismic sections should be written to a single output file. -
CHG Instead of automatically concatenating the results from some operation to obtain as few files as possible, the new default file creation strategy for GIPPtools is to start a new output file for every read input file. Judging from user feedback, this seems to be the expected behaviour by the majority.
So far, this change has been implemented formseedcut
,mseedrecover
,mseed2ascii
,mseed2mseed
andmseed2pdas
. You can use the new command line option--force-concat
to return to the former, concatenating output behaviour.
A nice side effect of the re-written output routines is that the utilities need (much) less memory and are more stable when applied to very large datasets. -
CHG Renamed the
--segment-length
command line option ofmseedcut
to--file-length
. The new name better describes the effect the option (writing files containing data of given length). -
CHG Renamed the
--output-sort
command line option ofmseedrecover
to--force-sort
. The new name aligns better with the other output options--force-overwrite
as well as--force-concat
and should be easier to remember by the user. -
CHG Renamed the
--rule-file
command line option ofmseed2mseed
to--rules
and renamed the--event-file
command line option ofcube2mseed
to--events
. The new names are shorter and better describe what the respective (file) arguments contain.
Release 2011.166
-
FIX The utility
edlcut
no longer crashes when the miniSEED input does not contain any relevant data for the requested time window. (This happened only under certain rare conditions.) -
NEW Added the options
--byte-order
,--record-size
and--encoding
to thecube2mseed
utility so that the user can influence the miniSEED output format. -
CHG Instead of creating a new output file for every shot/receiver gather requested by the user, the
cube2segy
andmseed2segy
utility will write all seismic sections into one single file. This was changed to ease the data import into other software packages. (You only need to import one single file instead of many files.)
Release 2011.119
-
UPG The
--include-pattern
option can be used more than once in the same command line. The given include patterns are cumulative. -
UPG Improved
cube2segy
to work with the extended, multi-file Cube data format of the next generation three channel units (currently in development). -
OPT Sped up the
cube2segy
utility to run two to five times as fast as before! Please note: Speed-up highly depends on the used Cube recorder settings, especially sampling rate and GPS cycling times. So, your mileage may vary… -
FIX The
cube2segy
utility will not longer crash when the time window of the trace to read starts before the begin of recording in the corresponding Cube file. (This only happened when there was no data for the begin of the time window but data for the end of the time window was available.)
Release 2010.321
-
UPG Improved
cubeinfo
to work with extended Cube file format of the next generation three channel units currently in development. Due to these changes the output format of the report generated bycubeinfo
has changed. -
UPG Added a new OVERVIEW output format to
edl2ascii
that will summarize miniSEED input streams consisting of many miniSEED records in an easy (for humans) readable format. -
CHG The
edlrename
utility will not longer overwrite already existing files. Instead, a new filename with an additional number in between basename and extension will be used for writing. To get the previous behavior of overwriting existing files use the new command line argument--force-overwrite
. -
OPT Improved the utilities that convert to SEG-Y (
cube2segy
andmseed2segy
). Instead of simply beginning the traces with the first sample after the respective start time, the sample closest to the start time is used. This reduces the timing error down to at most plus/minus half a sampling period. However, it also produces traces where the first sample lies before the requested window start time!
The difference between the requested begin of the trace and the time of the first sample is documented in the SEG-Y trace header (in field “lag A”). -
FIX The
cubeinfo
will not longer produce "NullPointerException" errors in the default INFO mode when reading from Cube files that were cut off prematurely (e.g. running out of power while recording).
Release 2010.202
-
CHG The
edl2segy
utility is now calledmseed2segy
. -
CHG The
edl2pdas
,edl2ascii
,cube2mseed
andcubeinfo
utilities will not longer overwrite already existing files by default. Instead, a new filename with an additional number in between basename and extension will be used for writing. To get the previous behaviour of overwriting existing files use the new command line argument--force-overwrite
. -
NEW There is a new
cube2segy
utility working just like the already existingmseed2segy
but reading Cube files as input instead of miniSEED files. -
UPG Added support for the newer XDR style output format of Seismic Unix to the
cube2segy
andmseed2segy
utility. (Before, only the old "native binary" format was supported.) -
UPG Added a GPS output format to the
cubeinfo
utility reporting time and position of all GPS blocks contained in a Cube data stream. -
UPG Made
edlrecover
more robust when recovering "almost-miniSEED files" (i.e. files that closely resemble valid miniSEED but still contain only binary garbage should no longer confuseedlrecover
). Changed the output subdirectory name to contain the "<year>" as well as the "<day-of-year>" when using the--output-sort
option. -
FIX Times given with more than six digits for the fractional part of the second (e.g. with nanosecond resolution) are now rounded to the closest microsecond instead of truncating the fractional part completely.
-
FIX Got rid of an internal integer overflow when extracting very large time windows (e.g. one year) from a miniSEED stream. This problem affected all utilities that use time windows to select data.
Release 2010.120
-
FIX The
cube2mseed
utility no longer writes miniSEED files that contain gaps or overlaps. Instead, a new file will be started if a discontinuity in the data stream is detected. -
UPG Improved tolerance of the Steim decoding subroutines. The GIPPtools utilities now can read more miniSEED variants than ever before.
-
FIX The
edl2segy
utility produced defect SEG-Y files under Solaris when using a Sun Java 1.6 virtual machine. (Strangely, it worked with a Java 1.5 runtime.) -
FIX Occasionally,
edl2segy
produced traces would contain one additional sample.
Release 2010.105
-
FIX
Edl2segy
works again! The previous release contained a subtle error that renderededl2segy
completely unusable! Fortunately, none of the other utilities was affected.
Release 2010.074
-
NEW Added support for the Cube data loggers. Use the new
cubeinfo
tool to get a textual summary about the content of a Cube file andcube2mseed
to convert Cube files to miniSEED format. -
NEW Added handling of miniSEED blockette #1001 to all GIPPtool utilities. This makes it possible to work with microsecond precision (instead of "only" with 0.0001s resolution).
-
OPT Completely rewrote the internal handling of miniSEED streams. Records are not longer decoded and encoded at every opportunity, which should speed up many GIPPtool utilities.
-
UPG Added a new CHECKSUM output format to the
edl2ascii
program. Use it to calculate a checksum over the samples of a continuous trace. MiniSEED header values are not included into the checksum calculation so that different miniSEED encoding scheme should still result in the same checksum, provided that the time series are identical. -
UPG The sample rate (of a miniSEED file) was added to the list of possible template variables of the
edlrename
utility. -
FIX A change in the sample rate between two consecutive miniSEED records was not always detected correctly.
-
CHG The
edlcut
andedl2edl
utilities will not longer overwrite already existing files by default. Instead, a new filename with an additional number in between basename and extension will be used for writing. To get the previous behaviour of overwriting existing files use the new command line argument--force-overwrite
. -
UPG The
edlcut
utility can now split a long miniSEED data stream into segments of given length. This can be used to produce e.g. "day files" out of a collection of input files. -
UPG New command line parameters (
--stop-time
,--trace-offset
) were added to theedlcut
utility to simplify the specification of a time window for cutting out samples from miniSEED data streams. -
CHG Minor change to the user interface. Error messages are not longer begin with the text SEVERE. Instead, they start with ERROR! After all, that is what they are. (Several users assumed that SEVERE is just some sort of fancy warning that can be ignored.)
Release 2009.244
-
NEW Added the new
edl2edl
utility.Edl2edl
can be used to selectively modify miniSEED header fields such as e.g. station, channel and network id. You can also use it to change the record size, byte order or encoding scheme of a miniSEED file. -
NEW Added Steim-2 encoding support to all GIPPtool utilities.
-
CHG Improved the
HEADER
output format of theedl2ascii
program to also report on record size, byte order and used data encoding scheme. -
UPG Added a new GMT output format to the
edl2ascii
program. Files created using the GMT parameter can directly be used as "multiple segment" input to thepsxy
command of the Generic Mapping Tools (also known as GMT, hence the format name). -
FIX Changed an internal filename filter that falsely discarded the dot (
.
) as an invalid (input) directory name. It is again possible to use the current working directory (aka.
) as starting point for a recursive search for input files.
Release 2009.026
-
UPG The
gipptools
start script (jointly used by all GIPPtool utilities) will detect a setGIPPTOOLS_JAVA
environment variable and use the respective Java Runtime Environment (JRE) instead of the automatically detected one. -
NEW Added the
edlrename
utility that can be used to systematically rename miniSEED files using a user provided "filename template". -
NEW Created a separate Microsoft Windows distribution of the GIPPtools software. (Note! The main difference between the Windows and Unix distribution is the used start script. For Unix a Bourne shell script is used while the Windows distribution relies on a Windows command file to start the various GIPPtool utilities.)
