cms-YYYY-simulated-datasets

This directory contains helper scripts used to prepare CMS MC Open Data release:

  • code/ folder contains the python code.
  • inputs/ folder contains input text files with the list of datasets for each year and input files with extra information for the datasets, such as DOI identifier and RECID.

Every step necessary to produce the final *.json files is handled by the cmc-mc/interface.py script. Details about it can be queried with the command:

python code/interface.py --help

The bash scrips in the current directory handle all the parameters of the interface:

  • make_local_cache.sh: creates a local cache of all information needed.
  • print_results.sh: creates a set of markdown and HTML pages with all the information available.
  • run_categorisation.sh: creates a set of markdown and HTML pages with the datasets splitted in their categories.
  • create_records.sh: create the final .json files: - one for the MC records - one for the configuration files

The steps to follow are:

voms-proxy-init --voms cms --rfc --valid 190:00
sh make_local_cache.sh
sh create_records.sh

Warning: creating a local cache takes a long time!

Issues

2011

The AODSIM files and metadata disappeared from McM. But the GEN-SIM are still there. The scripts do not handle this. It should be modified to get the oldest parent, find its prepId and then query McM. This way it should get the dictionary (cmsDriver script) and genFragment.

General

  • Creating a local cache for 2015 (or later) crashes in AFS due to the huge number of files in the cache folder. Running it on EOS might solve it. Or not.
  • Record json not tested with jsonschema.
