Codes unknown from TDataBasePDG

Hi all,

I am using root v6-16-00 with pythia8 and I want to try to simulate p-A collisions (actually p-O). Everything go smooth in pythia initialization but then I get:

Warning in TParticle::SetPdgCode: PDG code 1000020040 unknown from TDatabasePDG

So it seems (and indeed it is the case) that heavy-nuclei are not included in pdg_table.txt. Am I correct? and in case: is there an easy workaround for this problem?


ROOT Version: 6-16-00
Platform: Not Provided
Compiler: Not Provided

I guess this is related to this topic: Nuclei in TDatabasePDG
