Qtran: Cluster File Translator |
Qtran
version 3.6.3 is derived from QSAS 2.4.13 pre-release.
By default files are produced in the locally installed cdf version.
This version is available for Solaris (source), Linux (source), Windows(binary and source) and Mac OSX (binary and source)
Qtran converts files between the following formats...
Qtran is maintained by the Space and Atmospheric group in the Physics Department at Imperial College London as part of our role in the Cluster Science Centre within the UK. These formats and software, while designed with Cluster in mind, are quite general in applicability.
.Qtran is available as a compressed tar file containing source and documentation.
The Windows version also contains a Windows batch (.bat) script to allow running without
a command line (edit the Qtran.bat file and double click, diagnostics are written to file qtranlog).
On Solaris
and Linux platforms, cd to src in the Qtran directory and edit the
makefile to locate the local CDF installation.
Qtran is designed to work with CDF version 3.1 or later, but the
backward compatibility flag is set to ensure it writes files that can
be read by cdf 2.7 onwards. The restriction of using 3.1 onwards
is to allow reading of Themis data files that use epoch16 which is not
available in earlier versions.
To compile Qtran type 'make' at the prompt.
This will compile the Qtran executable and place it in the top level
Qtran directory.
On Apple Mac machines, download the Qtran.dmg installer and double click the Qtran package icon.
Once installed, typing Qtran without any arguments will produce a description of options.
Without any options (and just a filename as argument) Qtran will attempt to create a CDF file, unless the input file is a cdf file, in which case it will create a Cluster Exchange (.cef) file.
Options, if set, specify the input and output format, control whether an existing file will be overwritten, toggles record numbering, and specify verbose messages. See also the Mac specific readme file after Mac OSX installation.
NOTE: if the package will not install on a Mac or will only install 0 bytes, it may be necessary to delete the receipt from an earlier Qtran installation - delete the file /Library/Receipts/Qtran.pkg.
