Description

Dear Developers,

I was able to successfully test your (beautiful) DelphesCMSFWLite on a test CMS input file, in AOD format.
I then moved to something more interesting for us, namely try Delphes using as input a GEN-SIM format, which contains only information of Gen objects and the GEANT4 simulation output (i.e. no reconstructed objects).
I was not able to produce a valid output in this case, i.e. the output contained 0 particles (although the input had many many particles).

Have you tested DelphesCMSFWLite also on CMS GEN-SIM input files?
Kind regards
Leonardo

Dear Leonardo,

Thank you for testing DelphesCMSFWLite.

I've just tried to build DelphesCMSFWLite with CMSSW_5_2_5 and tested it with the /BJets_HT-1000ToInf_8TeV-madgraph/Summer12-START50_V13-v4/GEN-SIM data-set.

I had to add '-lEG' to the compilation command in DelphesCMSFWLite.sh. After that I could build and run DelphesCMSFWLite without any problem.

What CMSSW version are you using? Do you have any error messages?

Regards,

Pavel

Hi Pavel,

I recompiled as you suggested (I have added the lEG), but with CMSSW_5_3_2_patch4.
Unfortunately, the sample I was trying to run on was still producing an empty output, no error message at all.

To crosscheck I have tried to run on a similar GEN-SIM sample with respect to yours (same production campaign) and indeed it worked!
So it looks like the sample I was trying to process had something faulty, or maybe the whole Upgrade campaign is not compatible with this DelphesCMSFWLite version.

Have you tried to run on any sample designed for the LHC Upgrade studies, for eg
/WToLNu_TuneZ2star_14TeV-pythia6/Summer13-UpgrdPhase1Age0START_STAR17_61_V1A-v1/GEN-SIM
which are all produced with CMSSW 6XX releases? (the example here with CMSSW_6_1_2_SLHC2_patch3)

Kind regards
Leonardo
