If you are interested only in using the fit for validations you can skip this paragraphs and go directly to "RERECO VALIDATION instructions"

The .dat config file keeping the list of ntuples can be modified according to the needs adding or commenting unuseful ntuples or friend trees. It's then important to have a simple way to merge the trees in order to be able to manipulate, scan and plot variables from the ntuples. The ZFitter/script/GenRootChains.sh has been designed for this.

running the command:

./script/GenRootChains.sh -f data/validation/myConfigFile.dat

in the folder tmp/myConfigFile/ the s_chain.root and d_chain.root are created for MC and data respectively. The .root files have the TChains already defined, merging the files with the same treeName in the config file and adding the friends properly.

To work with ntuples you can do (see practical example below):

root -l tmp/myConfigFile/d_chain.root tmp/myConfigFile/s_chain.root
TTree * data = (TTree *) _file0->Get("selected");
TTree * signalA = (TTree *) _file1->Get("selected");
data    -> Draw("*");
signalA -> Draw("*");

Data/MC plots

A standard function for data/MC plots have been prepared and is available in python/plot.py. An example of how to use this library is in macro/standardDataMC.py

In the following you can find an example of production of data/MC plots with a config file with Moriond17 new regression

Simple:

./script/GenRootChains.sh -f data/validation/Moriond17_newRegr_v2.dat
python macro/standardDataMC.py absEta_0_1-gold "(160,80,100)" -d tmp/Moriond17_oldRegr/d_chain.root,"Moriond Data" -s tmp/Moriond17_oldRegr/s1_chain.root,"Moriond17 Madgraph MC"

./script/GenRootChains.sh -f data/validation/Moriond17_oldRegr.dat -f data/validation/Winter_2016_reReco_v1.dat
