Hello,

1, I want to use the FTF generator with the 'tut_sim.C' script in the tutorial/rho directory.
Doing that I set the 'inputGenerator' parameter to "ftf".
I receive the following error message:
----
/cvmfs/fairroot.gsi.de/fairsoft/oct17_root6/bin/root.exe: symbol lookup error: /lustre/nyx/panda/kmakonyi/PandaRoot/pandaroot_041117-src/built/lib/libM aster.so.0.0.0: undefined symbol: _ZN12PndFtfDirectC1EPKcS1_iS1_dib
----

2, I want to use the FTF generator to do a full detector simulation (based on the tutorias/rho/tut_sim.C script) to simulate prototn-antiproton _and_ proton-proton events.
How to pass the necessary 'mac' file to the generator?
(my first guess is that the
fRun->UseFtfGenerator("/lustre/nyx/panda/kmakonyi/WORK/DecChan/PbarA.mac ");
line will do this for me ... Can you confirm that?)

Hello Karoly,

There is still an issue with FTF and GEANT4. Please use FTF as standalone generator. You'll find the executable in your build/bin folder. Name the output in the form of ftf*.root. Then you can use this file as the value for inputGenerator="ftf....root". It should then be read by the simulation.

Cheers!
Ralf

Thank You Ralf!

An other question: is there any way (not the TFT) to generate proton-proton bckg events?

Regards,
Karoly

Using DPM (which si fully compatible w/o producing an additional file).

Yes, DpmDirect is working out of the box.
A fix for FTF is on the way to GIT, soon.

Thank You guys,

What I have to modify on the Dpm/DpmDirec in order to simulate proton-proton (and not proton-antiproton) events?

Thanx in advance,
Karoly

Sorry, I did not catch that you are interested in proton-proton, and not antiproton-proton.
As far as I remember, DPM is only with antiproton beam. Maybe Pythia could do the job, but at low energies Pythia is not very realistic.

Thanx Stefano,

So, it seems there is no other way only use the TFT ...

Best Regards,
Karoly
