Very simple ntuple maker class. Should compile out of the box using the "source compile.sh" command. Ntupler takes TopTree xml files as single argument and produces a very simple root tuple maked0plot.py is a very simple pyRoot analyser that books histograms and loops over the output tree.
use:
source compile.sh ./Ntupler <myxmlfile.xml> python -i maked0plot.py #
