Event reconstruction with PandoraPFA

Once you managed to create some events with Whizard, you certainly need to run some kind of reconstruction job. An example processor for a PandoraPFA job is available in:

/afs/desy.de/group/it/ilcsoft/v01-03-05/PandoraPFA/v02-01-dev/ldcprime_example_steering_file.xml

It will run following processors:

 <execute>
   <processor name="MySkipProcessor"/>
   <processor name="MyMaterialDB"/>

<!--digitizing everything-->
   <processor name="MyVTXDigiProcessor"/>
   <processor name="MyFTDDigiProcessor"/>
   <processor name="MyTPCDigiProcessor"/>
   <processor name="MySimpleLCalDigi"/>
   <processor name="MyLDCCaloDigi"/>
   <processor name="MySimpleMuonDigi"/>

<!--tracking-->
   <processor name="MyCurlKillerProcessor"/> 
   <processor name="MyLEPTrackingProcessor"/>
   <processor name="MySiliconTracking"/>
   <processor name="MyFullLDCTracking"/>

<!--particle flow-->
   <processor name="MyPandoraPFAProcessor"/>
   <processor name="MyMyPFOAnalysis"/>
   <processor name="MyLCIOOutputProcessor"/>
  <processor name="MyPandoraPFAEventDisplay"/>
 </execute>

You can copy the steering file to your working directory. Given you have installed Marlin, or linked the afs installation, just change the LCIOInputFiles and GearXMLFile, and you are ready to reconstruct your event sample.

$ Marlin ldcprime_example_steering_file.xml

Be aware that this will take a while, even if you are in the lucky position to own a fast computer. So if you intend to run on larger event samples, you may want to consider to run on the Grid.

Pandora will write the results in a root file PandoraPFAAnalysis.root.
