Hello Gate Users

I'm simulating the optical photons, I've defined a continuous crystal of
NaI(Tl) coupled to an array of 6x8 PMTs. I have defined also the optical
adder and I have the information of the amount of light received in each
PMT, but also I want to know the position of the singles calculated as the
 energy-weighted centroid of the different hit positions produced by the
gamma interaction into the crystal.

In the section 12.4 of the Gate Users guide v3.1.2 says it's to possible
to create two chains in parallel one containing the traditional singles
and one containing the singles generated by the optical photons.

In the macro I've just written:
/gate/digitizer/Singles/insert adder
/gate/digitizer/Singles/insert opticaladder
And the gateSingles.dat is completely empty.

but, when I comment out the optical adder ..
/gate/digitizer/Singles/insert adder
# /gate/digitizer/Singles/insert opticaladder
The  gateSingles.dat has the information of the traditional singles.

even more,  when I comment out the adder
# /gate/digitizer/Singles/insert adder
/gate/digitizer/Singles/insert opticaladder
The  gateSingles.dat has the information of the optical singles.

And finally I ran the simulation 7 days with the optical adder commented
out, and 7 days more with the adder commented out. Obviously using the
same seed file in each run.

I want simulate only once, with two digitizer chains in parallel, which
takes only 7 days, if it's possible off course.

P.S: I'm not using the last version of Gate, My configuration is :
Plataforma/Gate:  ROOT 5.14 / CLHEP / GEANT 4.9.0 (PATCH) / GATE
3.1.2                                            O.S.: Debian 4.0r1 AMD64
Kernel 2.6.24-etchnhalf.1-amd64

Thanks for your help,

Bye, Esteban Venialgo
