Software Tool Workflow CMS CERN-LHC

Description

The tool can be used to read events from CMS AOD files and convert them to a reduced NanoAOD data format for the purpose of education and outreach. Note that the tool is published for the documentation of the related datasets below and may need significant experiment-specific knowledge to be used.

Characteristics

1 files. 766.4 kB in total.

System details

This code can be used with the CMS Open Data VM environment.
Software release: CMSSW_5_3_32

How can you use this?

Setup CMSSW

source /cvmfs/cms.cern.ch/cmsset_default.sh
cmsrel CMSSW_5_3_32

Build module

cd CMSSW_5_3_32/src && cmsenv
mkdir -p workspace/AOD2NanoAOD && cd workspace/AOD2NanoAOD
# Put the files here
scram b

Test configuration:

cmsRun configs/*_cfg.py

The scripts create_job.py and merge_jobs.py can be used to submit the conversion of multiple files to an HTCondor batch system and merge the results to the final dataset.
