  Warning: Before you take any of below action,
           you must setup cdfsoft2 environment.
	   
General Description:
	This is a recipe for taking a file of events that are written by
	a matrix element generator such as MadGraph in Les Houches
	format, running the shower monte carlo Pythia on it to produce
	STDHEP format, converting this file to the CDF HEPG format using
	Sebastian Carron's code, and then running 4.9.0 CDF simulation
	and then Production on it.

	For example, the output files of MadGraph for many W and Z
	processes are in /cdf/data6a/frisch/MadGnew/DataSets. For each
	process there are two files: e.g. Zjj_events.dat, which
	contains weighted events (each event carries a weight with it,
	which can be very very small), and Zjj_unweighted_events.dat
	(each event counts as one event, like the ones we write to
	tape in the data). A third file, Zjj.log, tells how many of
	each kind of event there is, and other details. (One can look
	at the process by looking at the file results.html in the
	SubProcesses subdirectory with a browser).

1. To make phythia interface and produce HEPG file
   using MadGraph output

  /cdf/data5b/ukyang/mc/run_hepg.tcsh
  
  Command: run_hepg.tcsh "PROCESS_NAME"
       Example:  /cdf/data5b/ukyang/mc/run_hepg.tcsh Zjj

  (but be careful about input/output directory- for example, if you
  change GenBaseTMP in the script from data31b, make sure it has the
  same structure as unki's, e.g. a .logs subdirectory inside
  /mc/gen_data/. If you don't change anything, this should just work
  as is as long as the file is not there already.)



  now you have a HEPG output file

2. TO make CDFSIM using HEPG input file

   /cdf/data5b/ukyang/mc/sim/run_sim_v3.tcsh

  Command: run_sim_v3.tcsh "PROCESS_NAME"
  (again watch out input/output directory)

  Now you have a root file after cdfsim

3. TO make production file using simulated data.

   /cdf/data5b/ukyang/mc/sim/run_prod_mc_v3.tcsh

  Command: run_prod_mc_v3.tcsh input_sim_file_name
  (Here, this script take all of inputs
   with  input_sim_file_name*,
  For example, let's say you have following files,
  simu.root, simu.root_1, simu.root_2 
  from your simulation job, then if you just say
  "run_prod_mc_v3 simu.root", all of three files
  will be taken)
