the equivalent of particles in edm .root produced by pythia8 in cmssw to pythia6 .lhe file

Hi Siew Yan,

I guess that this question is for the MonteCarlo group of CMS.
I do not know which email/forum you can use to contact them since this method is probably only accessible to CMS member.

Cheers,

Olivier
