OSCAR analysis code to access AOD from ATHENA v 15

This page is deprecated, please see the OSCARSoftwareFramework page on the CERN twiki.

First log on to a machine with the ATHENA software (at Liverpool alpha, beta etc. (older), theta (newer))

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/15.5.4/CMT/*/mgr/setup.sh  
cmt config   

Setup a work directory

cd    
mkdir AtlasWork15   
cd AtlasWork15   
mkdir 15.5.4   
cd  15.5.4   

Setup ATHENA environment

source ~/cmthome/setup.sh -tag=15.5.4

Set up svn folloing the instructions to modify your .ssh/config found in

SVN help

The code can be viewed at

OSCAR SVN Repository

log into CERN.

/usr/kerberos/bin/kinit -5 username@CERN.CH 

Get the code packages needed for the example

cd $TestArea   
svn co $SVNGRP/Physics/Common/OSCAR/OSTools/trunk  OSCAR/OSTools  svn co $SVNGRP/Physics/Common/OSCAR/OSSelectors/trunk  OSCAR/OSSelectors  svn co $SVNGRP/Physics/Common/OSCAR/OSUtilities/trunk  OSCAR/OSUtilities  svn co $SVNGRP/Physics/Common/OSCAR/OSUserExamples/trunk  OSCAR/OSUserExamples  

or, alternatively, all the code packages:

cd $TestArea    
for pkg in `svn ls $SVNGRP/Physics/Common/OSCAR/`; do svn co $SVNGRP/Physics/Common/OSCAR/$pkg/trunk OSCAR/$pkg; done  

Make version.cmt files:

cd $TestArea/OSCAR

 ./OSUtilities/setup/createversion.sh 

[ Note: Subsequently all you need to do is setup

 source ~/cmthome/setup.sh -tag=15.5.4 

]

Compile

cd OSUserExamples/cmt    
cmt bro cmt config  
cmt bro source setup.sh  
cmt bro gmake    

[ Note: Subsequently for most compiles you can speed things up with:

  gmake -f ../i686-slc4-gcc34-opt/OSUserExamples.make QUICK=yes 

If this doesn't work use the full compile:

 cmt bro gmake 

]

cd ../share 

uncomment the lines for the file lists in osexamplez.py

e.g. for Liverpool it would be

 #include("liv.fileList_106050.PythiaZee.py")

NB if you want to run on files on the dpm you need to have a valid grid certificate and to set up ganga. At Liverpool do

source /batchsoft/atlas/grid/setup.sh -v 96:00

Run the code

cd ..  
mkdir run 
cd run  
athena.py   ../share/osexamplez.py >& Z.out &    

Plot the results

root -b -q ../Root/runFile.C 

If you want to run over data (!) DESDs then simply set 'isData=True' in osexamplez.py

To Create your own input file

a script is available in OSUserExamples/share/MakeInputfileList.py. To run:

source MakeInputfileList.py <dataset on atlasliverpooldisk>

Useful Links

To find out the Geometry version of the input file use:

      dumpVersionTags.py -f  [full path to inputfile]  

and look for a line like :

       GeoAtlas                                            ATLAS-CSC-02-01-00 

To find out whats on the AOD in v15 run:

 checkFile.py filename.pool.root
