• PIDCalibration wrapper.

Use correct samples to do PID calibration automatically according to the TRUEID of the particles, based on the tool described in https://twiki.cern.ch/twiki/bin/viewauth/LHCb/MeerkatPIDResampling

The following branches should exists in the tree:

1. [track name]_[TRUEID]
2. [nTracks]
3. [track name]_[P]
4. [track name]_[PT]

folders:

• config : configuration files for PIDCalib
• scripts : core scripts for PIDCalib

scripts:

• scripts/PIDCalib.py : Main script for PIDCalib
• scripts/PIDCorr_git_edit.py : The core script for PIDCalib (do not need to be modified)

config:

• config/config_samples_PIDCorr.yaml : configuration file for PID correction (transfomration)
• config/config_samples_PIDGen.yaml : configuration file for PID generation (resampling)
• config/pidcorr_run1.yaml : The file which defines the variables you want to correct for run2 MC
• config/pidcorr_run2.yaml : The file which defines the variables you want to correct for run2 MC

how to run?

• Source to enter lhcb environment by calling: source /cvmfs/lhcb.cern.ch/lib/LbEnv

• PIDCorr: sh run_pidcorr_local.sh

• PIDGen: sh run_pidgen_local.sh

what should I modify?

• The files in the config folder
• Modify PIDCorr and PIDGen to your needs

The complete list of PID configurations available in Run 1 and Run 2 can be obtained by running PIDGen.py without arguments: $ lb-run -c best --allow-containers --siteroot=/cvmfs/lhcb.cern.ch/lib Urania/v10r1 bash $ python $PIDPERFSCRIPTSROOT/scripts/python/PIDGenUser/PIDGen.py Note that Run 1 and Run 2 PID configurations have different names!
