Hi Nam,

there is something wrong with the procedure you are using. It seems you are feeding to Delphes the *.lhe file, which you should not be doing. Try to produce the hadronized file file (via Pythia or Herwig) and feed that one to Delphes instead.
If you are running through the MG+Pythia8 sequence you should have produced some *hepmc file. You can then run Delphes on that file via:

./DelphesHepMC cards/delphes_card_CMS.tcl output.root input.hepmc

Cheers,
Michele
