+ Ganga is a frontend tool for job definition and management with access to all grid infrastucture supported by ATLAS. Detailed Information about GANGA can be found in http://documentation.hepcg.org/res/ap3/w_301106.pdf.The following steps assume that you have a valid grid certificate.
  How to setup GANGA
-<
<
+ (a) Setup Grid environment and GANGA 
 The following two lines set up the Grid interface and GANGA using the newest version available on AFS:

+ (a) Setup Grid environment 

In order to use GANGA you should run the following commands in a clean shell.

Set up the grid environment and create a new proxy
  source /afs/cern.ch/project/gd/LCG-share/current/etc/profile.d/grid_env.sh
-<
<
+ source /afs/cern.ch/sw/ganga/install/etc/setup-atlas.sh
->
>
+ voms-proxy-init -voms atlas
  (b) Setup Athena
-<
<
+Set up your Athena environment as usual, for example under 15.6.0: 
 source ~/cmthome/setup.sh -tag=15.6.0 
 
 (c) Run GANGA
->
>
+Set up Athena as you would normally (for me this is) 
 source /home/robinson/athena/DiJets/15.6.7/cmthome/setup.sh 
 
 (c) Setup GANGA 

Now source the GANGA setup 

 source /afs/cern.ch/sw/ganga/install/etc/setup-atlas.sh
 
 Running GANGA
 Change directory to the run directory of the whichever package you are working on and then start ganga with:

 The most important options here are 
 j.application.option_file which contains your Athena jobOptions
 If the data is not present, you can go here to request replication: http://panda.cern.ch:25980/server/pandamon/query?mode=ddm_req


The Athena version that you request must be present at all sites that your job is sent to. You can check which versions are available at which sites by running:
