SAND-EMI

This packaged is a modification of Bing Guo's ecal muon identification code, it is the muon identification code for External Muon Identification of the SAND detector of the DUNE Near Detector.

Installation

**NOTE: ** always work from the top (package home) directory, run everything from here.

step - 1

Setting the path variables are crucial, therefore, one needs to first edit the set_env.sh script. This script has a path variable base_output_root_dir that needs to be edited, this is the location where you would like to store all your analysis files. Another variable is the file_list that contains list full absolute paths to the EDEPSIM root files that you are going to analyze using this package, an example list file will look like this:

_{^{/pnfs/dune/persistent/.../SENSDET_ECAL_AND_TRAPE_INTTRK_TRAPEZOIDAL_EXTMUID_2Layers_ActiveIRON_EXTMUID/STT_FHC_001_gsim002_5e17.192819.edep.root /pnfs/dune/persistent/.../SENSDET_ECAL_AND_TRAPE_INTTRK_TRAPEZOIDAL_EXTMUID_2Layers_ActiveIRON_EXTMUID/STT_FHC_002_gsim003_5e17.192819.edep.root /pnfs/dune/persistent/.../SENSDET_ECAL_AND_TRAPE_INTTRK_TRAPEZOIDAL_EXTMUID_2Layers_ActiveIRON_EXTMUID/STT_FHC_003_gsim004_5e17.192819.edep.root /pnfs/dune/persistent/.../SENSDET_ECAL_AND_TRAPE_INTTRK_TRAPEZOIDAL_EXTMUID_2Layers_ActiveIRON_EXTMUID/STT_FHC_011_gsim012_5e17.192819.edep.root /pnfs/dune/persistent/.../SENSDET_ECAL_AND_TRAPE_INTTRK_TRAPEZOIDAL_EXTMUID_2Layers_ActiveIRON_EXTMUID/STT_FHC_012_gsim013_5e17.192819.edep.root}}

We also have a file named nn_config.sh this contains the two NN cut values, one for the ECAL and the other for the EMI, initially you can set them to 0.5, but then after a training when you obtain a different cut as an output, you need to update that value. Once the editing of those variables are done, you can source this script: source set_env.sh

step - 2

To build the package, source the install.sh script from the top (package home) directory.

Running the code

Just source run_emi.sh N will suffice. Where N is the number of files (from the top) listed in the file_list file that you want to analyze.
