    // it is assumed that all files are in the same folder
    void SetFiles(boca::Phase const& phase) override

    // Define the cuts

        //  this cut is obviously not enough
        if (jets.size() < 2) return false;
        return true;

}

The analysis class is called like this

// Include the cut based analysis
#include "cut/Analysis.hh"

int main(){
  // Create an object of the cut based analysis
  cut::Analysis analysis;
  // Run the analysis and create efficiency plots
  analysis.Run(boca::Output::efficiency);
}
