Reconstruction

MarlinReco:

Required MarlinReco processors are outlined in MarlinReco Manual

Setting up Marlin:

My file directory used for reconstruction is ~/public_ppe/ExampleDSTAnalysis where I initialise ILCSoft with initialiseILCSoft.sh, build the Marlin processor using build_the_processor.sh and finally run Marlin_first_run.sh to set up the environment corretly.

Running Marlin:

Marlin steer_ild.xml

steer_ild.xml uses e-gun.slcio and corresponding GearOutput.xml which have been generated in Mokka and copied from ~/public_ppe/Mokka_Test/ParticleGun/

e-gun.slcio:

/generator/generator particleGun
/gun/particle e-
/gun/energy 100 GeV
/gun/momentumSmearing 5 GeV
/gun/position 0 0 0
/gun/direction 1 0 1
/run/beamOn 3000
exit

Looking At SLCIO Files:

Marlin lookAtFilenew.xml

Current Status

MarlinReco:

Required processors for reconstruction of e- particle gun:

• MyTPCDigiProcessor
• MyVTXDigiProcessor
• MySimpleCaloDigi
• MyTrackCheater
• MyLEPTrackingProcessor
• MyClusterCheater
• MyTrackwiseClustering
• MyWolf

Errors:

Unknown processors:

• MyTrackCheater
• MyClusterCheater
• MyTrackwiseClustering
• MyWolf

These are required for the Particle Flow Algorithm processor of type "Wolf" (also 'unknown') which creates the Reconstructed Particle Collection called 'RecoParticles' which will then be used to look at the physics of the events.
