1. Clone this repository with git clone https://github.com/jackdunger/oxsx.git --recursive if you've already cloned without the recursive flag just run git submodule update --init

2. Update env.sh to point to ROOT and scons installs e.g. ROOT_DIR = /software/..../root-5.34.30 SCONS_DIR = /software/..../scons-2.3.4

3. Do the same for GSL,armadillo, HDF5 and if these were installed to system dirs /user/lib etc. these can be left as empty strings ""

4. Run source env.sh && scons && scons units

5. Test the build was sucessful with ./tests/RunUnits

scons auto-generates a script that compiles and links your c++ against the source code and dependencies just run ./examples/compile.sh <your cpp file> to produce an executible of the same name

To create ntuples for oxsx run ./util/prune_flat_tree <path_to_file_to_convert> -treename <name_of_the_tree> <branch1> <branch2> <branch3> -newtreename <name_of_your_tree> -outputfile <name_of_your_file> -nevents <number_of_events>

• The name of the tree in an input file is optional, as a default it is "output"
• The name of the output file is optional, as a default is is <the_name_of_input_file>+"_oxsx.root"
• The name of the tree in an output file is optional, as a default it is "oxsx"
• The number of events of an output file is optional
