General informations for gridpack generation with MadGraph:
https://twiki.cern.ch/twiki/bin/view/CMS/QuickGuideMadGraph5aMCatNLO
NOTE: gridpack generation requires CMSSW not to be set, and won't work otherwise.
Madgraph datacards are generated for spin-0 (Radion) and spin-2 (Graviton) signals, produced through ggF or 'VBF' (is it really VBF here though??).
Mass hypothesis from 250 GeV to 3 TeV are used.
Example cards are available here:
- Spin-0, VBF: https://github.com/cms-sw/genproductions/tree/master/bin/MadGraph5_aMCatNLO/cards/production/2017/13TeV/VBFToXToHH/VBFToRadionToHH_M
- Spin-0, ggF: https://github.com/cms-sw/genproductions/tree/master/bin/MadGraph5_aMCatNLO/cards/production/2017/13TeV/exo_diboson/Spin-0/Radion_hh_narrow/Radion_hh_narrow_M900
- Spin-2, VBF: https://github.com/cms-sw/genproductions/tree/master/bin/MadGraph5_aMCatNLO/cards/production/2017/13TeV/VBFToXToHH/VBFToBulkGravitonToHH_M
- Spin-2, ggF: https://github.com/cms-sw/genproductions/tree/master/bin/MadGraph5_aMCatNLO/cards/production/2017/13TeV/exo_diboson/Spin-2/BulkGraviton_hh_narrow/BulkGraviton_hh_GF_HH_narrow_M900
These can be used as an input to getCards_allMassPoints.sh to get all desired mass points.
Once all cards are ready, the corresponding gridpacks can be generated using
genproductions/bin/MadGraph5_aMCatNLO/gridpack_generation.sh
submit_gridpack_llrt3.sh allows to call that script and run the gridpack generation on LLR t3.

These two linked were used to define the cmsDriver.py definitions in cmsRun_makeDrivers. None of these worked "out of the box" for me, so I did some tweaking to make things work. I'll make sure that everything is fine with MC experts before launching the actual production.
The drivers should be called in order from 00 to 04. 05 should be used to generate NANOAOD, but I still need to actually write/test it.
