[Gate-users] ROOT and breast phantom

[cindy Dong]

Hi,
I'm new to gate.Now I have 3 questions about it.

1.What's the meaning of ComptVolName1,ComptVolName2 in the ROOT file?

2.If I want to investigate the Scatter(include Copmton,Photoelectric and
Rayleigh),should i set all of them standard like
/gate/physics/gamma/select..... standard?
If not,how can i set them?

3.How can i define a Breast phantom?what are  the shape and material?

Thank you for your help!
