=== Which topdrawer version should I use with MadAnalysis? ===

Topdrawer is a SLAC software of which different versions are in circulation. For the automatic plotting after event generation MadAnalysis needs to be able to cut a topdrawer file in smaller files, convert them to postscript files and rotate the single plots automatically to put them in a web page. As the syntax for conversion and rotating plots is not the same in all version some errors, or even a complete stop of the MadGraph/MadEvent run might be expected if a non-default version of topdrawer is used for the automatic plotting.

We recommend the following pre-compiled versions of topdrawer:
   * (32 bit) Linux version available [attachment:td here]
   * Windows version available [http://www-group.slac.stanford.edu/beamphysics/codes/topdrawer/topdrawer.html here]
   * For Mac OS X look [http://theory.fnal.gov/people/parke/TD/td_mac_intel.tar.gz here].

The sources that are available from [attachment:td.tgz here] are '''not''' supported. (But might still be useful if neither of the above pre-compiled versions work or you are not using the automatic plotting, but running MadAnalysis by hand.)

Note: For most of the 64 bit linux version, the 32 bit version is in fact working. (Even if you see a warning message pointing you to this page)
Please first try the following:
1) quit mg5
2) relaunch it
3) run the following command
generate p p > e+ e-
output
launch -f
Look in the html if you see the plots. If yes then your version of linux supports the 32 bit binary.
If you don't have the plot (only a blank page), then you need to install the following libraries: ia32-libs.

One way to install this library is via the following command:
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs
