Dairy of Neutrino Cross-Section Tuning

Set Event Generator List and TUNE

IN $NUGEN_DIR/source/nugen/EventGeneratorBase/GENIE/GENIE2ART.h, there is a function called

 void SetEventGeneratorListAndTune(const std::string& evtlistname = "",
                           const std::string& tunename = "${GENIE_XSEC_TUNE}");

And we have to put it in the Begin Job of the art cpp module.

I installed NUISANCE and NuSystematics by following DirtTwo wiki.
After that, each time I logged in, I did source the qidong.sh file.

DUNE flux histogram

The neutrino flux for DUNE can be found here.

GENIE only comparison: AR23_20i_00_000 vs. N24_20i_02_11b

To generate flat root tree sample with nuisflat, take numu on Carbon-12 as an example:

bash makeCCQE.sh 
PrepareGENIE -i 14_1000060120\[1.0\]_618.root -f $(nuis flux NOvA_ND) -t 1000060120[1.0] -o CC_C12prep.root
nuisflat -i GENIE:CC_C12prep.root -o vAR23_C12QE.root

Notes on Mini Production 6.2

We have use N24_20i_02_11b as the genie tune tag for Mini Production 6.2 nominal sample, additionally we also have mean free path down samples.

Nominal FHC genie level only files

The sample directory is

/pnfs/nova/production/genie/R25-02-27-prod6genie.b/nd/N24_20i_02_11b/000120/12000/   

and samweb dataset name is

"defname:prod_genie_R25-02-27-prod6genie.b_nd_genie_N24_20i_02_11b_nonswap_fhc_nova_v08_full_v1_miniprod6-2_geniephyopt_nominal"

Nominal RHC genie level only samples

The root file directory is

/pnfs/nova/production/genie/R25-02-27-prod6genie.b/nd/N24_20i_02_11b/000121/12150/

and the SAMWEB dataset is

"defname:prod_genie_R25-02-27-prod6genie.b_nd_genie_N24_20i_02_11b_nonswap_rhc_nova_v08_full_v1_miniprod6-2_geniephyopt_nominal"

Data management

NOvA is still using the SamWeb to fetch dataset. So I borrowed the python script(samweb_listing.py) from ProtoDUNE to access defname files.

Workflow

Since submit_nova_art.py didn't work well during the MiniProd 6.2 validation period for a lot of reasons, I had to use bash script to run the GENIE file one by one. So I ran

bash loopart.sh list_sam_files.txt

And the fcl file I ran was Validation/fcl/validation_genieonly_job.fcl under novasoft development release.
