---+ Making Inputs for the Neural Net from AOD

This is just a small page that will contain any work-arounds/bug-fixes that we've found, that can't be applied in the code and require special action by your own good self.

1. In share/TtHHbbSetups.py:

<verbatim>
include( "AtlasGeoModel/SetGeometryVersion.py" )
include( "AtlasGeoModel/GeoModelInit.py" )
</verbatim>

Athena warns that both of these files are obsolete - this does not lead to an ERROR or WARNING, but nonetheless needs to be looked at.

2. In src/PreselectLeptons.cxx:

<verbatim>
    const EMShower* shower;
    if ((*elecItr)->author() != egammaParameters::AuthorUnknown){
      trackIsolationEnergy20 = m_trackIsolationTool->trackIsolationEnergy((*elecItr)->trackParticle(),0.2);
      trackIsolationEnergy30 = m_trackIsolationTool->trackIsolationEnergy((*elecItr)->trackParticle(),0.3);
      trackIsolationEnergy40 = m_trackIsolationTool->trackIsolationEnergy((*elecItr)->trackParticle(),0.4);
      shower                 = (*elecItr)->detail<EMShower>(m_showerContainerName);
      //CCT: shower - seems to have stopped working in 15.6.0.2 for data made with r838 (v15.3.1.6)                                                                               
      //was giving a seg fault as it tried to get etcone20 even if "shower" had not been successfully obtained!                                                                   
      if (!shower) {
        mLog << MSG::WARNING << "Invalid EMShower pointer!" << endreq;
      }else{
        etcone20               = shower->etcone20()/pT;
        mLog << MSG::INFO << "shower->etcone20() = " << shower->etcone20() << ", pT = " << pT << endreq;
      }
    }
</verbatim>

The warning message appears an awful lot - also, don't think this influences the Net inputs, but still should be looked at - do we need to get anything from the shower?

3. From the ye olde code, I noticed a 'placeholder' warning to check that W and top masses used in the sensible states are the same as in the generator (this hasn't been done yet).  Also, perhaps we can tighten the sensible cut on the W mass?  Seems rather wide at the mo (25GeV)....

Manifests through error strings such as the following example (though there are many other errors, all related through the final INFO message):

This is a problem with the databases - the fix to this is to get a newer DB installed, so you just have to speak to Tom Doherty.  If you are running on *MC* this is sufficient.  If you are running on *data*, then you need to also do the following:

<verbatim>
export ATLAS_POOLCOND_PATH=/afs/cern.ch/atlas/conditions/poolcond/catalogue <http://cern.ch/atlas/conditions/poolcond/catalogue>
export FRONTIER_SERVER="(serverurl=http://lcgft-atlas.gridpp.rl.ac.uk:3128/frontierATLAS)(serverurl=http://oratest02.pic.es:3128/pic-frontier)(proxyurl=http://nat005.gla.scotgrid.ac.uk:3128)(proxyurl=http://fal-pygrid-45.lancs.ac.uk:3128)"
</verbatim>
