Building
and running the Jet/Met root maker
A
more advanced example is to run the Root maker of the Jet and
MET group. Since the original Buildfile causes trouble we replace
it with the one that we can find in the
top area of this exercise.
cmscvsroot
ORCA
cd ${TOP}/ORCA_7_6_0/src
cvs co -r ORCA_7_6_0 JetMetAnalysis/domain
cd JetMetAnalysis/domain/test
mv BuildFile BuildFile_org
cp ${TOP}/BuildFile .
scram b shared
scram b bin
eval `scram runtime -csh`
rehash
cd
This
will create the JetMet executable in your binary directory:
ls
../../../../bin/Linux__2.4/JetMet
We
also want to create the shared library libRM.so which can be
used to analyze the root
file created by the JetMet root maker:
cd
${LOCALRT}/src/JetMetAnalysis/
cvs co -r ORCA_7_6_0 JetMetRoot
cd JetMetRoot/
make
will
create
libRM.so
cd
$SCRIPTS
setup kerberos
setup fbsng
fbs submit zprime_jj_jmntuple.jdf 8 10000 5
To
analyze this data:
cd
$ANALYSIS
set i=10001
while ( $i < 10008 )
dccp ${PNFS_PATH}/${i}/pool_orca/zprime_jj_jetmet${i}.root
.
@ i++
end
root
.L
${ROOTSYS}/lib/libPhysics.so
.L libRM.so
TFile *f = new TFile("zprime_jj_jetmet10001.root")
.x dijet3.cint
Should
produce a plot like the one below (just with tiny statistics).
If you want
more statistics
one
can find
6000 Z' -> jj events in
/pnfs/cms/WAX/2/wenzel/zprime_jj/
to
copy the root trees use the following command:
set
i=10001
while ( $i < 10021 )
dccp //pnfs/cms/WAX/2/wenzel/zprime_jj/${i}/pool_orca/zprime_jj_jetmet${i}.root
.
@ i++
end
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
