  • Permission do not denied on my system (how it can be!!??)
  • In addition, there are not /etc/ld.conf.so, ldconf and $LD_LABRARY_PATH => cygwin had been not installed correctly?

• Changing parameters at GenExample_cfg.py
  • MinE? : 10GeV -> 7TeV
  • AddAntiParticle? : True -> False
  • cms.Process : "Gen" -> "Gen+Sim"
  • Result above

  • Please see the pp14TeV_gen.root(before) and pp14TeV_GENSIM.root(after), file size is almost same both two

• I couldn't find any available data such as pt, eta, phi and so on at pp14TeV_gen.root.
  • Even if when I use gate ..... In this case, gSystem->Load("libFWCoreFWLite.so") and AutoLibraryLoader?::enable() work propably
