LIGOtools Package: dtt

This package contains a version of the Diagnostic Test Tools utilties for offline use. Type dtt to bring up the main menu, from which you can launch a Fourier Tools window, etc.

Also included in this package are fantom, a utility for copying and transforming LIGO data (e.g. retrieving data from tape or from the HPSS archive, and writing it to local disk or to a DMT shared-memory partition); lidax, a graphical user interface to the functionality of fantom; and a number of lower-level utility routines.

Frequently Asked Questions related to this package

Notes

At present, this package is only available as a binary distribution for Solaris.
The distribution file installs a complete set of the root libraries for use only by the dtt programs. This frees you from having to install root separately, yet it should not interfere with any version of root that you might already have installed. Note that these libraries make the distribution file rather big.
If you want to be able to run Data Viewer, you must also have the dataviewer LIGOtools package installed.
Color support has been improved in DTT version 2.0. For best results, the computer should be in 24-bit TrueColor mode. Here are instructions for doing this.

Documentation

Diagnostic Test Tools can read data stored on disk in frame files, and the interface has been greatly improved in version 2.0. See these Notes on using Diagnostic Test Tools with data on disk.
Some documentation is available via the Global Diagnostics System web page.
Lidax can be started from the dtt main menu window or by typing lidax on the command line. For usage instructions, see the Lidax Quick Start Guide.
An example for using fantom, assuming you have to read a large tar file but want to extract a few channels only:
```
   fantom -c fantom.conf
```
with fantom.conf something like:
```
   in 0 open tape:///home/sigg/frames/H-681029160.F.tar -f "*.F"
   out 0 open dir://.
   out 0 type FF1N1C0
   out 0 channels {"H0:PEM-*"}
   out 0 flush
```
This will produce 1-second frame files in the current directory.
Technical information about Fantom and Lidax is available here.

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.
