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
