[Gate-users] Problem with Initialization of Geometry

[Xinjie Cao]

I guess the problem is about the brain phantom related file,
range_atten-brain.dat as followed:
```
4
0 0 Air false 0.0 0.0 0.0 0.2
4 4 Water true 1.0 0.0 0.0 0.2
5 5 Water true 0.0 1.0 0.0 0.2
14 15 Water true 0.0 0.0 1.0 0.2 ```
Is anyone familiar with this file? Can anybody explain it explicitly? Like
what is the '0' before Air meaning?
Any response will be highly appreciated! Thank you!

Best,
