This is a simple set of macros for looking at AnalysisTree files. It is currently configured to use ROOT 6 and relies on CMake for building. Compilation is not necessary though. Details on avoiding it appear below.

The easy way to get going is to install ROOT6 via Homebrew using the following steps:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install homebrew/science/root6
git clone https://github.com/bcarls/anatreeloop.git
cd anatreeloop
source setup_homebrew.sh
mkdir build
cd build
cmake ..
make

When starting with a fresh login, setup everything with this:

source setup_homebrew.sh

git clone https://github.com/bcarls/anatreeloop.git
cd anatreeloop
source setup_gpvm.sh
mkdir build
cd build
cmake ..
make

When starting with a fresh login, setup everything with this:

source setup_gpvm.sh

If you make a change, recompile the library with this:

cd build
make

To run the code using the AnaTreeLoopData module and the compiled library, do the following using python:

python scripts/run_AnaTreeLoopData.py -s anatreefile.root

To run the code without compilation, the Python script needs slight modification, replacing this line in run_AnaTreeLoopData.py:

ROOT.gSystem.Load("build/AnaTreeLoop/libAnaTreeLoop")

with these:

ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeTracks.cxx");
ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeFlash.cxx");
ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeVertex.cxx");
ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeTruth.cxx");
ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeAlgs.cxx");
ROOT.gROOT.ProcessLine(".L AnaTreeLoop/AnaTreeLoopData.cxx");

I also have an example Python script that does not need compilation here:

scripts/run_AnaTreeLoopDataNoCompile.py
