MCatNLO Step 3

On this page we will use the <>.event files that were produced by MCatNLO (see step 2) as input to Herwig. Using the Athena program we will use Herwig to have the top quarks decay and finally we will produce a combined ntuple (CBNT) and Pool file as was done for Rome.

1) Create a few directories

cd /project/atlas/users/ivov/MyMCatNLO/
mkdir MyMCatNLO_BASICS
mkdir MyMCatNLO_OUTPUT
mkdir MyMCatNLO_OUTPUT/InputAndLogFiles

2) Get necessary files required for Athena running

Since we are using MCatNLO we require a joboptions file and some other Athena-specific python files. In addition a file called inparmMcAtNlo.dat is expected that provides some input variables.

cd MyMCatNLO_BASICS
get_files PDGTABLE.MeV
get_files PartPropSvc.py

Copy 2 'basic'files here

cp /afs/cern.ch/users/i/ivo/public/MCatNLO_scripts/joboptions_MyMCatNLO_Step3.py.BASIC .
cp /afs/cern.ch/users/i/ivo/public/MCatNLO_scripts/inparmMcAtNlo.py.BASIC .

The script that is defined (step 4) will take this In the joboptions file there are a few places where the script (see step 4) will set unique variables for each job.

3) Get script and taylor it to your needs

cd /project/atlas/users/ivov/MyMCatNLO/
cp /afs/cern.ch/users/i/ivo/public/MCatNLO_scripts/ShipOff_MyMCatNLO_Step3.py .
