Attention: Please see the github wiki for most up to date documentation  https://github.com/markrosslonergan/whipping_star/wiki

#Instructions for GPVM based building and running. While in base git directory
source .setup.sh 

#To Build, should work out of the box on GPVM with above setup
cd build
cmake ..
make

This will build the SBNfit source and libraries, as well as executable example programs in build/example
The included simple examples are not physically accurate, just toy MC! 

cd examples

#The first example builds a covariance matrix from eventweight std::map<std::string,std::vector<double>> objects
./example1 --xml example.xml --print

should have 4 output files, first two data, second two human readable plots
	EXAMPLE1.SBNspec.root	: The central value spectra
	EXAMPLE1.SBNcovar.root	: The full and fractional covariance matricies
	SBNfit_spectrum_plots_EXAMPLE1.root    : The central value plots, but subchannels stacked to represent a channel
	SBNfit_covariance_plots_EXAMPLE1.root  : The covariance matricies plotted as TH2D nicely. Inside directory individualDir is all the individual variation matricies

#The second example loads up the computed covariance matrix and makes a plot of the chi^2 as you scale the signal for stats and stats+sys
./example2 --xml example.xml

should have 1 output. EXAMPLE2_plots.root containing a simple TCanvas showing the chi^2 behaviour
