 All the scripts required to make the histogram templates are in the [**Analyzer**](./Analyzer) directory.

 bash script. The bash script will also unset the CMSSW runtime environment if you had done ```cmsenv```earlier. 
 This ensures there are no conflicts between the ROOT version that you have just set up and the version in CMSSW.
 
 Producing the histograms is a two-step process. The steps are:
 
 1. Make skimmed ntuples for skimmed NanoAODs by using the [```SkimNtuples.py```](./Analyzer/SkimNtuples.py) script. This will make the histogram making step faster. Example to run the script can be found in [```RunLocal_SkimNtuples.sh```](./Analyzer/RunLocal_SkimNtuples.sh).
 
-2. Make histograms by running over the ntuples with the [```MakeHistograms.py```](./Analyzer/MakeHistograms.py) script. Example to run the script can be found in [```RunLocal_MakeHistograms.sh```](./Analyzer/RunLocal_MakeHistograms.sh).
+2. Make histograms by running over the ntuples with the [```MakeHistograms3D.py```](./Analyzer/MakeHistograms3D.py) script. Example to run the script can be found in [```RunLocal_MakeHistograms.sh```](./Analyzer/RunLocal_MakeHistograms.sh).
 
 The histograms will be saved in the ```histos``` directory. Run [```haddHistos.sh```](./Analyzer/haddHistos.sh) to merge all Data histograms for each year. The paths to the skimmed NanoAODs and skimmed ntuples are specified in [```SampleList.py```](./Analyzer/SampleList.py).
