An event display is a graphical tool for viewing detector structure
and events. BaBar's tool of choice is called WIRED (Version 3).
The display can include tracks, hits on tracks, unused hits, Dirc Hits, Emc
and Ifr clusters, and more. You can click on hits, clusters, etc. to get a pop-up attribute window with physics quantities relevant to the selected objects, and you can output a variety of high quality graphics formats all the way from GIF and JPG, though Vector PostScript and PDF.
To start the WIRED browser, type
> wired -exp babar
Click on the folder icon in the upper left-hand corner to start the
"open file" dialogue. When you select one of the files, the system will
display an image of the first event in that collection.
To be taken through this procedure step by step, go to Starting the WIRED client from the CM2 WIRED webpage.
This page also has up-to-date instructions on how install the required
software, view a display of an event of your choice in a collection of your
choice, and build and run your own event display server.
For more detailed instructions on how to use WIRED, go to the SLAC WIRED Users Home Page.
WIRED is a actually the client part of a client/server system. The server is called HepMiniApp. (Older BaBar documentation may refer to older servers,
but as usual you want the "Mini" one, because Mini means up-to-date.) WIRED
is a standalone java application, which means that it does not depend on BaBar
software. So you can use it at SLAC, where it is already installed --- but
you can also install and run in on your laptop.
How to Install WIRED
An existing set of servers takes care of the actual BaBar Computing
environment work and database connectivity. Users wishing to access
more obscure data or reconstruction versions can access such data by
running their own personal WIRED servers. The different servers
are described here.
To learn how to create and run your own server, check out
Customized Servers for BaBar WIRED
There also exists an SRT package for BaBar WIRED users containing
useful scripts for installing and running WIRED:
> cvs co BbrWiredUser
In particular, there is a handy script in this package for installing
a new version of the WIRED client in your private work area:
and a number of scripts geared toward running a public event display.
For help on application of WIRED to BaBar-specific tasks, contact
the BaBar Wired
Liaison. For more generic WIRED help, contact the central WIRED
e-mail account, email@example.com.
