Hello Anastasia,

It is not possible, because for FTF generator in PandaRoot, I apply to
Geant4 lib and can not change compilled sourse files of FTF.
But, you can obtain only inelastic events using FtfEvtGen/main.cc .
For this, you need to add in the main.cc after line
----------------------------------------------
if(std::abs(pd->GetBaryonNumber()) < 2)
----------------------------------------------
line
---------------------------------------------
if( (n>2) || ((abs(id)!=2212)&&(n==2)) ) {
------------------------------------------------
and after line
----------------------------------------------
new((*fEvt)[cnt++]) TParticle(fparticle);
----------------------------------------------
to add
--------------------
}
--------------------
After this, it is needed to compile FTF.
About "MeV" or "GeV", thank you, I didn't draw attention to it.
Just now, I have changed and commited main.cc .
Output particles are stored in GeV.
Good luck
Aida
