Hi Giuseppe,
Thanks for your reply...I tried it but it still doesn't solve the problem.
I know that I can use your specified macro to create a collimator step by
step. However, I do want to use the option given in the guide using the
/gate/SPECThead/daughters/insert parallelbeam
This has a parameter that specifies the septal thickness
/gate/colli/geometry/setSeptalThickness 0.2 cm
I guess I will be able to track the septal penetration using
/gate/output/analysis/recordSeptalPenetration true
/gate/output/analysis/setSeptalVolumeName collimator
I've tried this using the macro that you suggested and it doesn't work. I
assume that you need to set the septal thickness shown in the guide's
example. If there's another way that someone knows to make it work please
let me know.
Thanks,
Carlos
