Hello Yuncheng,

unfortunately I still do not have much more input concerning this problem… It seems Geant4 version related, that’s why is still working with an old version of Gate as you pointed out.
If you want you can have a look at the following link for more info (thanks to David for the link)

thanks for your feedback! We will update the examples.

Dear Alessio,

It works with the modification! Thanks for your help.
It is interesting that I tried the same example1/ on a GATE v6.2, and it worked there with the C11[0.0] notation without problem.

Best,

Yuncheng

Dear Yuncheng

The „problem“ is related to the filtering itself describe at line 115 of your main.mac file:

/gate/actor/carbonMap/particleFilter/addParticle   C11[0.0]

if you change this line with the following one

/gate/actor/carbonMap/particleFilter/addParticle   C11

you should get your wanted output for C11. Honestly, I am still not sure what those brackets are standing for…
I will come back to you with more input.

Hope it can help meanwhile!

Cheers
Alessio

Dear All,

Maybe it has been addressed previously, I am wondering if anyone have successfully run the sample at example/example_Radiotherapy\example1. I tried it with both proton and carbon as incident particles in the mac/main.mac file. Both times I had the energy data output, while the C11 files were all empty. The primary beam number was 1e5. The GATE version is 7.1.

How should I change the GATE code or the example1 code to make it produce secondary particles correctly?

Thanks!

Yuncheng
