The different samples
A short description of the sample necessary for the Rome tt analysis:
T1: TTbar events using MCatNLO. Fully hadronic events were rejected.
T2: TTbar events using MCatNLO. Fully hadronic events were rejected and at least 1 top has 500 GeV
A7: W+4jet events using AlpGen.
Note 1: Given the limited manpower and diskspace we only collected a subset of all file formats (no 'simul' and ESD files for example).
Note 2: In producing the TopNtuples for the A7 sample some AODs were discarded since they gave problems. The TopNtuples have a bit less events than the AODs.
A short description of the sample generated using TopReX. All samples were reconstructed with Full Simulation (GEANT4) unless specified.
4511: W-gluon single top production.
4520: ttbar pair production. W- decays to leptons (e, mu), W+ decays to jets
4521: ttbar pair production. W+ decays to leptons (e, mu), W- decays to jets
4522: ttbar pair production. Dilepton sample.
4530: W-top associated production. W+ decaying to hadrons, W- decaying to leptons.
4531: W-top associated production. W- decaying to hadrons, W+ decaying to leptons.
4540: s-channel single top production.
4599: Wbbbar background sample. ATLFAST ONLY.

How to get the Ntuples to your institute:
- To copy all TopNtuples from NIKHEF to your institute just get the following small python script called Get_TopNtuples_From_NIKHEF.py and run it: ./Get_TopNtuples_From_NIKHEF.py. Note that for the AOD's you will have to do a bit more sophisticated and get a list of ascii files first (more later).
- Another script you can use as example on how to get the files to your institute is DataFetch.py which was constructed by Akira Shibata.
Athena release 11:
The ESD/AODs created using Athena release 11 were made by Nabil Ghodbane and can the corresponding files can be found on his CASTOR directory:
