Step 4: Digitizing the Events with ORCA

Here we will digitize the events produced by OSCAR with ORCA (Object-oriented Reconstruction for Cms Analysis)

cd $TOP
cmscvsroot ORCA

You will need to login the first time using cvs login and password: 98passwd

scram project ORCA ORCA_7_6_0
cd ORCA_7_6_0/src
cvs co -r ORCA_7_6_0 Examples/ExProduction
cd Examples/ExProduction/
scram build shared
scram build bin
eval `scram runtime -csh`
rehash

ls ../../../bin/Linux__2.4/

cd $SCRIPTS
setup kerberos
setup fbsng
fbs submit zprime_jj_orca.jdf 8 10000 5

This will submit job with 8 processes into the batch queue where each process will process 5 events

Continue to next step

1. General setup
2. Event generation on the farm with CMKIN (Pythia), Analysis of the generator level output
3. Simulate the events with OSCAR
4. Digitize with ORCA
5. Run a small ntuple maker ( from Stephan's ORCA tutorial) looking at Calorimeter quantities
6. Run the JetMet ntuple maker and make some plots
