Error in G4ParticleHPChannelList

I simulate secondary neutron field from reactions of proton on water target enriched with 18O with Geant4.11 and QGSP_BIC_AllHP Physics list and I am getting this error:

It seems, that there is some problem with the data for alpha on 18O. Do you know, how to correct it? Since alpha are not too important for my simulation, I would be ok with the fact, that only models would be used for alpha particles, do you know how to do that. Thank you very much for your help.

8_18_Oxygen data does not exist for Alpha in the G4TENDL database, but it should take the cross sections from the closest isotope. I do not understand why you get such an error, and indeed I cannot reproduce it. Anyhow, if you do not really care, you can simple do
cp $G4ALPHAHPDATA/Inelastic/CrossSection/8_17_Oxygen.z $G4ALPHAHPDATA/Inelastic/CrossSection/8_18_Oxygen.z

cp $G4ALPHAHPDATA/Inelastic/F02/8_17_Oxygen.z $G4ALPHAHPDATA/Inelastic/F02/8_18_Oxygen.z

In my version of G4TENDL1.4, there are data for 8_18_Oxygen in Alpha/Inelastic/F02. What version of G4TENDL do you use? It is true, that in the preceding version G4TENDL1.3.2 there were no data for 8_18_Oxygen and I did not have this problem, so the solution could also be, to delete 8_18_Oxygen.z…

As it is stated in the error message, it comes from these lines in G4ParticleHPChannelList:

if ( running[nChannels-1] == 0 )
   //This happened usually by the miss match between the cross section data and model
   if ( targA == -1 && targZ == -1 ) {
      throw G4HadronicException(__FILE__, __LINE__, "ParticleHP model encounter lethal discrepancy with cross section data");

   G4cout << "Warning from NeutronHP: could not find proper reaction channel. This may cause by inconsistency between cross section and model.  Unchanged final states are returned." << G4endl;

   //For Ep Check create unchanged final state including rest target 
   G4ParticleDefinition* targ_pd = G4IonTable::GetIonTable()->GetIon ( targZ , targA , 0.0 );
   G4DynamicParticle* targ_dp = new G4DynamicParticle( targ_pd , G4ThreeVector(1,0,0), 0.0 );
   unChanged.SetMomentumChange(aTrack.Get4Momentum().vect().unit() );
   G4ParticleHPManager::GetInstance()->GetReactionWhiteBoard()->SetTargA( targA ); 
   G4ParticleHPManager::GetInstance()->GetReactionWhiteBoard()->SetTargZ( targZ ); 
   delete [] running;
   return &unChanged;

Would it be possible to just alter this part of code to skip that particular track and not to abort the whole simulation?
What will happen if I just comment out the “if ( targA == -1 && targZ == -1 )” section?

Thank you for your reply.

I am not responsible of this code, but I can try to help you. But I need to reproduce your error. Can you send me your code? If you prefer you can do it privately to

I sent you an email. Thank you.
