===== Athena Event Displays =====

==== VP1 (VirtualPoint1) ====

=== Setup ===
On ''atlas1.hep.anl.gov'':
<code bash>
export AVERS=$1
export TEST_AREA=$HOME/athenaTestarea/$1

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh
asetup 17.2.11.12,AtlasProduction,slc5
</code>
I did this last in ~/athenaTestarea/17.2.11.12.2/

=== HepMC to POOL ===
Download this job options file.
<code bash>
get_files Example_McAsciiReader_jobOptions.py
</code>
Edit ''Example_McAsciiReader_jobOptions.py'' where it specifies an input filename so that it reads from your file (line 51) and change ''MCEVENTKEY='GEN_EVENT' '' (line 38).

Run
<code bash>
athena Example_McAsciiReader_jobOptions.py
</code>

=== AtlasG4_tf.py ===
Run
<code bash>
AtlasG4_tf.py' --autoConfiguration=everything --inputEvgenFile=myOutputEvgenFile.root --outputHITSFile=myOutputHITSFile.root --geometryVersion=ATLAS-GEO-20-00-01 --conditionsTag=OFLCOND-MC12-SIM-00 --maxEvents 5
</code>

=== Digi_tf.py ===
Run
<code bash>
Digi_tf.py --autoConfiguration=everything --inputHitsFile=myOutputHITSFile.root --outputRDOFile=myOutputRDOFile.root --conditionsTag=OFLCOND-MC12-SIM-00
</code>

I've received an error here complaining about a mismatch in the GEO tag. I edited the ''runargs.HISTtoRDO.py'' file to have the following
<code python>
from GeoModelSvc.GeoModelSvcConf import GeoModelSvc
GeoModelSvc.IgnoreTagDifference = True
</code>

=== Reco_tf.py === 
Run
<code bash>
Reco_tf.py --inputRDOFile=myOutputRDOFile.root --outputAODFile=myOutputAODFile.root --autoConfiguration=everything --preExec='jp.Rec.doWriteAOD.set_Value_and_Lock(True)'
</code>

=== vp1 ===
In a fresh shell run:
<code bash>
export AVERS=$1
export TEST_AREA=$HOME/athenaTestarea/$1

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh
asetup 17.7.3.6,AtlasProduction,slc5
vp1 /path/to/myOutputAODFile.root
</code>

I had to switch athena versions in order to get the object tracks to show up in ''vp1''.
