	| Hi all, 
 i have again the problem that McTruthMatch always returns false, but at another level.
 
 Now I try to match the whole decaytree of my Lambda LambdaBar decay.
 
 What I do:
 
 
 
RhoCandList ppbarsystem;
ppbarsystem.Combine(lambda, lambdabar);
ppbarsystem.SetType(88888);
for(int b=0;b<ppbarsystem.GetLength();b++)
{
    if(theAnalysis->McTruthMatch(ppbarsystem[b],2,true))
		{
		// fill some histogram
		}
}
 Output created:

Info in <PndMcTruthMatch::MctMatch>: Investigating in particle with pdg: 3122 and 2 daughters

Info in <PndMcTruthMatch::MctMatch>: rejected by not existing MC truth of daughter zero
 This appears for all my llbar combinations.
 Seems that the MCTruth tree is not build. Should this work and something is going wrong, or am I doing something wrong?
 
 Best regards
 
 Simone

	| Hello Klaus, 
 yes, I can confirm this. Would it help to insert the PDG code before in the files?

 In addition I have a new problem.
 In the next line my analysis task crashes with the following output :

There was a crash.

 This is not correlated with the verbose level, I had this before. I cant see a correlation with my code. Sometimes the codes runs without a crash, sometimes not

	| Hi Klaus, Hi all 
 
 | Quote: |  | I believe this it due to a mismatch of the PDG codes used by EvtGen and those in TDatabasePDG.
 
 | 
 
 Can't I insert somehow the 88888 pdg code in the database manualy so that the match works?
 
 I saw in this post:
 https://forum.gsi.de/index.php?t=tree&goto=14689&rid=1562&S= ab06a719b66b530ae5b7a8f7a9f6cdd3&srch=TDatabasePDG#msg_14689
 that one can do it, but I dont know what to fill in for some the variables.
 
 
virtual TParticlePDG*   AddParticle(const char*  Name,
                                    const char*  Title,
                                    Double_t     Mass,
                                    Bool_t       Stable,
                                    Double_t     DecayWidth,
                                    Double_t     Charge,
                                    const char*  ParticleClass,
                                    Int_t        PdgCode,
                                    Int_t        Anti=-1,
                                    Int_t        TrackingCode=0);
 Does someone know?
 
 best regards

	| Hi Simone, 
 
 you could try something like
 
 
 TDatabasePDG::Instance()->AddParticle("pbarpSystem","pbarpSystem",1.9,kFALSE,0.1,0,"",88888)
I think, for the truth match only the pdg code is important anyways.
 
 
 Best regards,
 Klaus
