What is your input file?

you should have something like that inside of
the Init method -----
like

InitStatus PndTofHitProducerIdeal::Init()
{

// Get input array
fPointarray = (TClonesArray*) ioman->GetObject("TofPoint");

//TofPoint is the branchname you want to read from
//input file

if ( ! fPointArray )
{
std::cout << "-W- PndTofHitProducerIdeal::Init: "
<< "No TofPoint array!" << std::endl;
return kERROR;
}

and then, you define where you want to save the output

//Create and register output array
fHitArray = new TClonesArray("PndTofHit");
ioman->Register("TofHit", "Tof", fHitArray, kTRUE);

return kSUCCESS;
}


In Exec to get fPointarray information,

// Loop over TofPoints
Int_t nPoints = fPointArray->GetEntriesFast();

for (Int_t iPoint = 0; iPoint < nPoints; iPoint++)
{
point = (PndTofPoint*) fPointArray->At(iPoint);

// Create new hit
new ((*fHitArray)[iPoint]) PndTofHit(trackID, detID,
point->GetDetName(),time, t1, position,dpos,iPoint, point->GetEnergyLoss(),1);

}

i hope it can help you

cheers
alicia.
