Making predictions

nue

Note: some of these steps are overkill. In principle you only need to make predictions, hadd everything, move on.

  1. Run on the grid
  2. Hadd the grid outputs in some folder inside provisional_singles
    mkdir -m 776 /nova/ana/nu_e_ana/Ana2017/Predictions/provisional_singles/v6e
    cd  /nova/ana/nu_e_ana/Ana2017/Predictions/provisional_singles/v6e
    for up in Up Down; do for xp in xp_prop xp_combo; do nice hadd_cafana pred_"$xp"_EnergyCVN2D_full_nueconcat_RelativeCalib"$up"_v6e.root /pnfs/nova/scratch/users/$USER/ana2017/v06d/RelativeCalib"$up"_nue_"$xp"/pred_"$xp"_EnergyCVN2D_full_nueconcat_RelativeCalib*; done; done
    
  3. In latest, create or modify a symlink to the latest prediction files (in this example, new files that are not individual XSec are saved under "other")
      cd /nova/ana/nu_e_ana/Ana2017/Predictions/provisional_singles/latest/other
    
      for xp in nxp xp_prop xp_combo; do 
      for i in AllSmall RelativeCalibUp RelativeCalibDown; do 
      ln -s -f ../../v6e/pred_"$xp"_EnergyCVN2D_full_nueconcat_"$i"_v6e.root pred_"$xp"_EnergyCVN2D_full_nueconcat_"$i".root; 
      done; done
      
  4. Update the hadded prediction files (note: some elements might be commented; this simple script is not version controlled)
      cd /nova/ana/nu_e_ana/Ana2017/Predictions/provisional_singles/latest
      source run_hadd_singles.sh

void plot_prediction_systs(const std::string& filename_sh, const std::string& period="full", const std::string & filename_nom = "")
  std::vector<TString>  xptype = {"pred_nxp"};
  if (!isNumuAna) xptype = {"pred_nxp","pred_xp_combo", "pred_xp_prop"};
  else            xptype = {"pred_nxp","pred_xp_numu"};

  std::vector<SNameDef> systnames = GetShiftNames2017();
  //std::vector<SNameDef> systnames = GetShiftNames2017("allNueReduced");                                                                                                                       
  //std::vector<SNameDef> systnames = GetShiftNames2017("allNumuReduced"); 

Nue

For nue, in order to check all systematics, we split the task into FD plots with prop + ND plots (ETA 8 min), and FD plots with combo (ETA xx).
There are 6 files required for this in /nova/ana/nu_e_ana/Ana2017/Predictions/provisional_singles/latest/
This is a hack but it is clearly labeled, not necessary with smaller syst lists, and resulted from one analyzer's traumatic memory usage issues.
Substitute p by c in the filenames to switch between prop and combo
