mv {rivet,agile}*sh /atlas/lester/usr/local/rivet

following instructions on http://projects.hepforge.org/rivet/trac/wiki/GettingStarted

Then I copied the build directoreies to

/usera/lester/proj/utils/MCGen/Rivet-1.6.0



Use with:

First 4 lines make us use the compiler and python versions that LCG is expecting, not slc5 defaults:

# Makes web pages under ./plots/ANALYSIS_NAME/ from Rivet.aida
rivet-mkhtml --mc-errs Rivet.aida
# In addition, this makes lots of dat files in ./plots/ANALYSIS_NAME/*.dat (one for each plot) that contain both styles and data.  These can be edited (eg to remove plot styles).  Then you can "re-run" the plot creation with

make-plots --pdfpng plots/LESTER_TEST1/*.dat

# Alternatively, you could put somthing like this in a file LESTER_TEAS1.plot:
cat << EOF > LESTER_TEST1.plot
# BEGIN PLOT ./plots/LESTER_TEST1/abc.dat
XTwosidedTicks=1
Title=Moo
LogY=0
RatioPlotYLabel=Ratio
XLabel=
YLabel=
YTwosidedTicks=1
Legend=1
# END PLOT

# ... add more histograms as you need them ...
EOF

and then do 

rivet-mkhtml --mc-errs -c LESTER_TEST1.plot Rivet.aida

and it will get the web-page right first time.

You can control herwig pt cuts (at generation) by adding lines like


set /Herwig/Cuts/JetKtCut:MinKT 30.0*GeV

to the WHATEVER.in file that makes the WHATEVER.run file ...

See B.5 of  http://arxiv.org/abs/0803.0883 and examples in

/usera/lester/proj/utils/MCGen/herwig-fun-2/../Herwig++-2.5.1/src/defaults/Cuts.in

and LESTERs own LHC.in file: /usera/lester/proj/utils/MCGen/herwig-fun-2/LHC.in ... 

export NUM=500000
( cd /usera/lester/proj/utils/MCGen/herwig-fun-2 ; Herwig++ run LHC.run -N$NUM -d1 >& Herwig++.log ) &


Turning on hepMC writing in herwig++:

insert LHCGenerator:AnalysisHandlers 0 /Herwig/Analysis/HepMCFile
set /Herwig/Analysis/HepMCFile:PrintEvent 10000000
set /Herwig/Analysis/HepMCFile:Format GenEvent
set /Herwig/Analysis/HepMCFile:Units GeV_mm
set /Herwig/Analysis/HepMCFile:Filename /tmp/fifo.hepmc


and then running with -N50000 (or whatever)
