cms-2015-simulated-datasets

This directory contains helper scripts used to prepare CMS 2015 open data release regarding MC simulated datasets.

• code/ folder contains the python code.
• inputs/ folder contains input text files with the list of datasets for each year and input files.

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

Make sure to start voms-proxy before creating cache

voms-proxy-init --voms cms --rfc --valid 190:00

Warning: creating a local cache might take a long time!

Here is how to run the record creation.

First, create EOS file index cache:

$ python3 ./code/interface.py --create-eos-indexes ../cms-YYYY-simulated-datasets/inputs/CMS-2015-mc-datasets.txt

lhe_generators

python3 code/lhe_generators.py 2> errors > output &

• This will get lhe generator parameters for datasets listed in ./inputs/CMS-2015-mc-datasets.txt
• This script must run this in lxplus or with mounted EOS
• number of threads is set to 20 which is ideal for lxplus

⚠️ There are many cases with various steps to get generator parameters for LHE -see #97-. Thus, in some few cases, the script MIGHT not work as expected so make sure to read it, check errors, and make any necessary tweaks
