This code performs staged BDT analyses using root files as in- and output format.

Dependencies

ROOT version ≥ 6.05.02 compiled with TMVA and MathMore
FastJet
FastJet Contrib (must be compiled with CXXFLAGS=-fPIC)
Boost version ≥ 1.56 (Optional, Range, Units, Operators, Iterators)

The BoCA code makes heavy use of modern C++ features. The limiting factor for the minimal supportet compiler version is given by the use of generic lambda functions. Therefore the compiler version must be

GCC version ≥ 4.9
Clang version ≥ 3.4 (which might rely on a recent GCC version)

Installation

The configuration process depends on CMake ≥ 3.1. For the build process you can use

the following is tested on recent ubuntu, scientific linux and mac installations
```
  mkdir build
  cd build
  cmake ..
  make -j
```
for quicker compilation install ccache and ninja-build and use
```
  mkdir build
  cd build
  cmake -G Ninja ..
  ninja
```

for mac you can also use (still install ccache)

  mkdir build
  cd build
  cmake -G Xcode ..
  xcodebuild

if you have trouble installing ROOT ≥ 6 with GCC ≥ 5 you can configure it with
```
  cmake -DCMAKE_CXX_FLAGS=-D_GLIBCXX_USE_CXX11_ABI=0 -Dmathmore=ON -Dbuiltin_gsl=ON -GNinja ..
```
unfortunately this means that all other dependencies also have to be compiled with the cxx11 abi switched off e.g. for FastJet you have to use
```
  ./configure CXXFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0
```
and for FastJet Contrib
```
  ./configure CXXFLAGS="-fPIC -D_GLIBCXX_USE_CXX11_ABI=0"
```

Usage

Examples are listed here.

Each analysis needs a dedicated Analysis class, a set of Tagger classess and a main.cpp file. The Analysis class contains the global information of the analysis, such as file names, path names, variables names etc. Every Tagger class tags or reconstructs one specific particle or signature. Each analysis needs at least one dedicated Tagger. The main.cpp defines the order in which each Tagger is passed to the Analysis.
