NanoAOD-like Ntuple producer tool for CMS Run1 data

How can you use this?

NanoAODRun1ProducerTool is a package to be used with the CMSSW software. In contrast to the CMS NanoAOD format which is centrally produced from MiniAOD by the CMS data processing system, this code generates an equivalent format from AOD with this completely independent code provided by the CMS open data group. The output files are available for selected Run1 data and simulated samples on this portal and they can be analysed independently.

For any additional production, CMSSW is available in the CMS Open Data environments: in the CMS Docker container and in the CMS VM image.

• For the Docker container, install the corresponding Docker container.
• For the VM image, follow the instructions for the virtual machine installations for 2010 or 2011-2012 data.

To download and run the NanoAODRun1Producer code, follow the instructions at https://github.com/cms-opendata-analyses/NanoAODRun1ProducerTool.

For more information about physics object access, see the CMS Open Data Guide web site.

The output files from the NanoAODRun1Producer package are in a NanoAOD-like research-level Ntuple format for CMS Run1. There is a large overlap in functionality and content between NanoAOD-Run1 and the usual CMS NanoAOD such that common analyses are possible. The files are in the ROOT tree format and their analysis does not require the use of CMSSW and CMS Open data environments.
