LIGOtools Package: wat
This package contains the Wavelet Analysis Tool software developed at
the University of Florida, including the utilities:
- WatFrComp to compress a frame file (lossy) using
wavelets. The output is a frame file (but with data stored in a
format which cannot be unpacked by the frame library at this time).
- WatFrUnComp to uncompress a file generated by
WatFrComp.
- WatFrStat to print out channel-by-channel compression
factors.
Authors:
Sergey Klimenko
and Andrei Sazonov
Version 1.62
Release date (as a LIGOtools package): May 9, 2001
Notes
- This package includes the wavelet analysis library
libwavelet.a in $LIGOTOOLS/lib, as well as several
associated header files in $LIGOTOOLS/include.
- This package does not include a shared-object library (as
would be required for using it within ROOT).
- There is an example Makefile that can be used to process a
large number of frame files, after suitable hand editing. The
file is located at
$LIGOTOOLS/packages/wat/active/etc/Makefile_batch or at this link.
Documentation
- The main source of documentation is the web page
maintained by the authors.
- Typing WatFrComp, WatFrUnComp, or
WatFrStat by itself gives a brief description of the
arguments.
Distribution files
Normally, you should use the ligotools_update utility to
download and install new packages or new versions of existing
packages, since it automatically figures out what packages need to be
updated. However, if you wish to do so manually, then click on the
name of the appropriate distribution file (below) with the
right mouse button and choose "Save Link As..." from
the popup menu. Note that you must save it on your disk with exactly
the same name as it has on this web site. After the file has been
downloaded, do:
ligotools_install <file>
where <file> is the file which was downloaded. This
procedure will be quicker if the environment variable
LIGOTOOLS is set to the main LIGOtools directory.
