WZG selector

This repo is deprecated due to the env upgrade. Used for local test only.

Based on NanoAOD Tools: https://github.com/cms-nanoAOD/nanoAOD-tools

Dedicated for WZG analysis on lxplus environment

Download and setup 

cmsrel CMSSW_10_6_19
cd CMSSW_10_6_19/src
cmsenv
git clone https://github.com/cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools 
cd PhysicsTools/NanoAODTools
scram b
git clone https://github.com/Senphy/nanoAOD-WVG.git
cd nanoAOD-WVG

We need to update some files for official NanoAOD-tools. Also we need to scram the new modules.

mv modules/* $CMSSW_BASE/src/PhysicsTools/NanoAODTools/python/postprocessing/modules/
mv update_for_nanotools/for_prefire/L1PrefiringMaps.root $CMSSW_BASE/src/PhysicsTools/NanoAODTools/data/prefire_maps/
mv data/* $CMSSW_BASE/src/PhysicsTools/NanoAODTools/python/postprocessing/data/
cd $CMSSW_BASE/src/PhysicsTools/NanoAODTools
scram b

Baseline selection local test

In WZG_seletor, WZG_Module.py is designed for basic selection (e.g. pt cut). Use WZG_postproc.py for local test.

cd $CMSSW_BASE/src/PhysicsTools/NanoAODTools/nanoAOD-WVG/WZG_selector
python WZG_postproc.py -h

arguments:

  • -f specify the input file. For local file e.g. /afs/xxx.root. For DAS file e.g. root://xxx. In condor mode it should be dataset name e.g. /WZG/XXX/NanoAODSIM. If an input file is not provided, assume this is a crab job.
  • -m Run mode. Normally use local. condor mode is designed as an interface for condor_for_postproc.py in condor folder.

DAS_filesearch.py is designed for returning LFN from given dataset. And store LFN into given filepath_GIVENFILENAME.txt. Then it will call test_ValidSite_cfy.py to search the valid site which can get access to the LFN.


Condor mode

Condor mode mainly is designed for MC production and postproceeing MC samples. Since the HTCondor sometimes can't get access to some sites, it is still recommended to use crab to handle MC samples. In condor folder, condor_for_postproc.py is designed for preparing codes and submitting them to HTcondor. The purpose is to run over samples on DAS in parallel. It has -f arguments to load input json.

First you need to setup grid certification

voms-proxy-info -voms cms -valid 192:0

Modify Proxy_path in condor_for_post.py according to you own settings

cd condor_for_mc
python condor_for_postproc.py -f input.json

The production code is prepared for generating private signal samples

Crab mode

Crab mode is designed for data/MC.

cd crab

The crab mode is based on official nanotools. See reference: https://github.com/cms-nanoAOD/nanoAOD-tools/tree/master/crab

The crab_help.py is designed to simplify the repeated process. And the input.json is a sample for how to provide input for crab_help.py. WZG_crab_script.sh is the executed code on crab and will call the WZG_selector for postprocessing.

First you need to generate the cfg file for crab job.

python3 crab_help.py -f input.json -m prepare

It will create a folder that with cfg files inside automatically. Noticed that some paths in crab_help.py need to be changed according to different user.

Then you can submit crab jobs with:

python3 crab_help.py -f input.json -m submit

Similarly, you can use -m status, -m resubmit, -m kill to batchly operate crab jobs.
