Beginning with the ATLAS dataset

Hello,
I’m trying to get started with Atlas dataset, using their git repository of code files fro analysis and plotting of data.
I’m using these commands, I have only downloaded a few data/mc file (only for this particular analysis)

python RunScript.py -a TTbarAnalysis
python PlotResults.py Configurations/PlotConf_TTbarAnalysis.py

Runscript command is running fine but the second command is giving these errors

/Downloads/root$ python PlotResults.py Configurations/PlotConf_TTbarAnalysis.py
Drawing plot: jet_pt
Error in <TFile::TFile>: file results/data_Egamma.root does not exist
Traceback (most recent call last):

    Paintables = collectPaintables(configuration["Paintables"])

    return getHistogram(subcontribution, doScaling)

Hi,
you should rather ask the author(s) of that git repository.
