Warning in FairPrimaryGenerator [message #16467]

Hi,

when using an EvtGen decay file with a PDG code not in TDatabasePDG, FairPrimaryGenerators prints for every single decay some warning like

 -W FairPrimaryGenerator: PDG code 88880 not found in database. This warning can be savely ignored

Is there a (verbose-)switch which allows to suppress this warning? If not, would it be possible to implement something to get rid of this warning?

Best and thanks,
Klaus

what about adding the particle in the database by adding the following in the simulation macro?!?

TDatabasePDG::Instance()->AddParticle("pbarpSystem0","pbarpSystem0",fIni.M(),kFALSE,0.1,0, "",88880);

Hi Johan,

yes, I believe that was my own suggestion some time ago, but this workaround nevertheless is unconvenient. And since the warning itself says, that it savely can be ignored, I don't know why I should read this message 10000 times...

Best,
Klaus

indeed, I learned this trick from you actually Wink

And you are right, why giving a warning at all when it is completely save to ignore it... bit ironical.

Hi,
If you don't want to see the warning on screen then comment the line 234 in source code /pandaroot/base/sim/FairPrimaryGenerator.cxx . then compile it again, it will not display that warning.

 cout << "\033[5m\033[31m -W FairPrimaryGenerator: PDG code " << pdgid << " not found in database. This warning can be savely ignored.\033[0m " << endl;

Thank You

Hi,

thanks for the hint, but I'd really like to have some official switch, so that I don't need some patch or workaround every time again.

Best,
Klaus

I think the message should stay there, since if you do some error in your generator you will never realize w/o such a message.
The point would be to set these TParticle in some standard class called at the beginning of each macro.

Again, if I'm aware of that problem in some case, I'd like to have the possibility to switch it off by sth like

primaryGen->PrintWarnings(kFALSE);

Best,
Klaus

some thing verbose like will be good in this case I have not seen any loop on verbose in the source code FairPrimaryGenerator.cxx. But one can put the loops like

if (verbose>1){
cout << "\033[5m\033[31m -W FairPrimaryGenerator: PDG code " << pdgid << " not found in database. This warning can be savely ignored.\033[0m " << endl;
}

Thank you

However, this is the wrong place to ask, since FairPrimaryGenerator is a FairRoot class.

I somehow overlooked the FairRoot forum, I'm gonna post the same message there again.

Best,
Klaus
