Environment Setup

lxplus

First time setup (installing conda environment):

cd ennironment
sh setup.sh

Activate the conda environment:

conda activate qe

How to Run?

To see full possible options:

python start_here.py --help

# To run truth (parton-level) analysis
python start_here.py --truth 

# To run reco (detector-level) analysis
python start_here.py --recon

# To run both truth and reco analysis
python start_here.py --truth --recon

Control different decay channels:

'pi_pi', 'lep_pi', 'lep_lep', 'lep_rho', 'pi_rho', 'rho_rho'

For now, only pi_pi works.

Data Folder

Data on lxplus can be found in /afs/cern.ch/work/y/yulei/public/qe/data folder. Please copy the whole data folder to your working directory, or a soft link:

ln -s /afs/cern.ch/work/y/yulei/public/qe/data data

python3 start_here.py pi_pi --truth --in_dir ./data --out_dir ./output

For now, the data folder should contain one root file for each process. Merge them before using.
