Checking out and running AtlasHbb to make corrected D3PD and FlatTuple files.

Introduction

This page describe my learning steps in using the common Glasgow framework used by H->bb analyses to create D3PD and/or FlatTuple files. I will adapt this later to be adapted later for the ZH analysis.

ssh -Y ppepc137.physics.gla.ac.uk

Then open an xterm terminal.

xterm

Create the folder we will work in.

export TEST_AREA=/home/abuzatu/TestArea
mkdir $TEST_AREA
cd $TEST_AREA

Now cvs checkout

source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh
svn-grid-proxy-init
svn co https://ppesvn.physics.gla.ac.uk/svn/atlas/AtlasHbb/tags/AtlasHbb-00-00-16/

Setup the configuration files

cp AtlasHbb-00-00-16/scripts/AtlasHbbScript.sh .
cp AtlasHbb-00-00-16/scripts/GlaNtpScript_atlas.sh .
chmod u+x AtlasHbbScript.sh GlaNtpScript_atlas.sh

Check out and build AtlasHbb and GlaNtp into GlaNtpPackage

./AtlasHbbScript.sh -a 16.6.5 -p 00-00-16 -g 00-00-40

Look at help sheet for using AtlasHbbScript

./AtlasHbbScript.sh -h

Produce input file list for you to run over and produce a corrected D3PD

cd Grid_GlaNtpPackage/ModifiedD3PD
./getFiles.sh -test -cutword -storeFiles $TEST_AREA/GlaNtpPackage/testsvn1/AtlasHbb-00-00-16/BaseAnalysisCode/InputFiles/

Now we can test to run over these input files

cd $TEST_AREA
./AtlasHbbScript.sh -a 16.6.5 -p 00-00-16 -g 00-00-40 -r -n -runtype corrections -process T1 -cutword

The code seems to ends well.

NtupleAnalysis: INFO: Finished
BASEANALYSIS: Done

There were events that did not pass the preselection, so they were stored with a zero bit. This is normal, not a warning.

Info: CutWord: Event Failed Preselection. 0 Bit Stored
TupleModifier::ProtectedEvent: Called entry 9967 with isValid= 1
Info: CutWord: Event Failed Preselection. 0 Bit Stored
TupleModifier::ProtectedEvent: Called entry 9968 with isValid= 1
Info: CutWord: Event Failed Preselection. 0 Bit Stored

Now we check the output file which is the .root file created here

cd $TEST_AREA/GlaNtpPackage/testsvn1/AtlasHbb-00-00-16/BaseAnalysisCode/OutputFiles/
ls 
root.exe *.root

I get many warnings like this

Warning in <TFile::ReadStreamerInfo>: corrections_T1__SMD3PDv16modifier.root: not a TStreamerInfo object

It means that first we have to setup ROOT by setting up Athena.

cd $TEST_AREA/
export AtlasSetup=/data/atlasb04/software16_slc5_gcc43/AtlasSetup
alias asetup="source $AtlasSetup/scripts/asetup.sh"
export ATHENA_VERSION=16.6.5
asetup $ATHENA_VERSION,here
echo $AtlasArea
cd $TEST_AREA/GlaNtpPackage/testsvn1/AtlasHbb-00-00-16/BaseAnalysisCode/OutputFiles/
ls 
root.exe corrections_T1__SMD3PDv16modifier.root
