AOD access from ATHENA v 13 
  Instructions on how to run the Liverpool/Birmingham code that accesses AOD in Athena with overlap removal. 
First log on to a machine with the ATHENA software  (at Liverpool alpha, beta  etc., up, down  etc.)
 Setup your cmthome directory
cd
mkdir cmthome
cd cmthome
Download the file   
requirements  and put it in cmthome:
Set up ATHENA for first time
source /batchsoft/atlas/athena/13.0.40/CMT/*/mgr/setup.sh
cmt config
Setup a work directory
cd
mkdir AtlasWork13
cd AtlasWork13
mkdir 13.0.40
cd  13.0.40
Setup ATHENA environment
source ~/cmthome/setup.sh -tag=13.0.40,gcc323
Set up cvs and log into CERN
export CVSEDITOR=pico
/usr/kerberos/bin/kinit -4 username@CERN.CH
 Get the code
cd $TestArea
cvs co groups/blanalysis/BLBasic groups/blanalysis/BLUserExamples
[ Note:  Subsequently all you need to do is setup source 
 ~/cmthome/setup.sh -tag=13.0.40,gcc323
 ]
 Compile
cd groups/blanalysis/BLUserExamples/cmt
cmt bro cmt config
cmt bro source setup.sh
cmt bro gmake
 Run the code
cd ../run
athena.py Zee_jobOptions.py >& Zee.out &  
athena.py Zmumu_jobOptions.py >& Zmumu.out &
Plot the results
root -b -q ../Root/runFile.C
  Photon Example 
To run photon example:
cd $TestArea
cvs co groups/blanalysis/BLPhotonExamples
cd groups/blanalysis/BLPhotonExamples/cmt
cmt config
source setup.sh
gmake
cd ..
mkdir run
cd run
cp ../share/* .
athena Photon_jobOptions.py > test.log &
