Step 5: Running a small ntuple maker
Running a small ntuple maker
Here we use an existing program that fills some standard calorimeter quantities into a
Root tree. The example consists of 5 source files,
one .cpp, two .cc and two .h files. Here you can find an image showing how these files depend on each other.
cd ${TOP}/ORCA_7_6_0/src
cmscvsroot ORCA
cvs co -r Tutorial031114 Examples/Tutorial
cd Examples/Tutorial
scram build shared
scram build bin
eval `scram runtime -csh`
rehash
now the ExTutTree executable should be on your path
cd ${SCRIPTS}
setup kerberos
setup fbsng
fbs submit zprime_jj_ntuple.jdf 8 10000 5
Let's go to the analysis area to have a look at the Root Tree. First we stage in the produced files from Mass storage then we make a few plots.
cd $ANALYSIS
set i=10001
while ( $i < 10009 )
dccp ${PNFS_PATH}/${i}/pool_orca/ExTutTree${i}.root .
@ i++
end
root
root [0] .L T1.C
root [1] .x plotT1.C
root [2]
should produce something similar to the plots below plotting some simple reconstructed quantities (just with less statistics).
