How to use the Event Display
The CDF event display is a very handy tool for seeing what your events look
like. Both real and simulated data can be displayed. A variety of "views"
(2d, 3d, silicon, whole detector) are available. These are documented
here .
How to access the event display
A version of cdfSim corresponding to code version $CDFSOFT2_DIR (the most
recent frozen production version) can be found in
$CDFSOFT2_DIR/bin/Linux2-KCC_4_0/evd.exe . If you really want
to make your own executable, do this:
- type newrel -t X mycdfsim , where X corresponds to your
desired code version
- type cd mycdfsim to move into that directory
- type addpkg RootMods to copy the relevant code into your
subdirectory.
- type gmake RootMods.evd to compile the evd.exe executable.
- Your executable can now be found in the mycdfsim/bin/Linux2-KCC_4_0
subdirectory.
How to run the event display
You will find a script in $CDFSOFT2_DIR/bin/Linux2-KCC_4_0/
called evd . This launches the event display and generates
the directives file on the fly. Normally you shouldn't need to change anything
here, just make sure that at the end
$CDFSOFT2_DIR/bin/Linux2-KCC_4_0/evd.exe /tmp/evd.tcl.`whoami`
... the full path of the executable is that which you intend to use.
To launch the event display, type ./evd_tcl_path data_path , where
evd_tcl_path is the full directory path to your evd tcl-generating
file, and data_path is the full path of the data you wish to look
at.
