Requirements

• ROOT6
• C++11 compiler
• CMake >= 2.8 (lx-cluster: cmake28 executable)
• Boost

Build

mkdir build; cd build
cmake ..
make

On lx-cluster:

• use CMSSW_7_4_X
• use cmake28 instead of cmake

Run

Execute run.x (created in the build directory). Without any arguments, a test module is run. Meaningful modules can be chosen as arguments:

$ run.x --help
Usage: ./run.x module1[ module2[...]] [options]
Allowed options:
  -h [ --help ]              produce help message
  -f [ --fraction ] arg (=1) Fraction of events to process
  --release                  Release mode (don't draw version labels)

Output

Plots are stored as canvases in a root file. The view.py script can be used for browsing the file, it sets the right styles.

Adding new modules

To add a new module, create a new <module>.cpp file in src/modules. The entry function has to be extern "C" void run() {...}. Add <module> to the list in src/modules/CMakeLists.txt
