FLAF

FLAF - Flexible LAW-based Analysis Framework. Task workflow managed is done via LAW (Luigi Analysis Framework).

How to install

1. Setup ssh keys:

   • On GitHub settings/keys
   • On CERN GitLab profile/keys

2. Clone the repository:

   git clone --recursive git@github.com:cms-flaf/Framework.git FLAF
   

3. Create a user customisation file config/user_custom.yaml. It should contain all user-specific modifications that you don't want to be committed to the central repository. Below is example of minimal content of the file (replace USER_NAME and ANA_FOLDER with your values):

   fs_default:
       - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/'
   fs_anaCache:
       - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/'
   fs_anaTuple:
       - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/'
   fs_anaCacheTuple:
       - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/'
   fs_histograms:
   - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/histograms/'
   fs_json:
   - 'T3_CH_CERNBOX:/store/user/USER_NAME/ANA_FOLDER/jsonFiles/'
   analysis_config_area: config/HH_bbtautau
   compute_unc_variations: true
   store_noncentral: true
   

How to load environment

1. Following command activates the framework environment:

   source env.sh
   

2. For the new installation or after you implement new law tasks, you need to update the law index:

   law index --verbose

   voms-proxy-init -voms cms -rfc -valid 192:00
