[Gate-users] help on using phase space file

[Yuncheng Zhong]

Dear All,

I was trying to use a phase space file as the photon source in a PET simulation and encountered a problem. The phase space file was a  .root file. When GATE started, I always got an error message,

Error in <TChain::SetBranchAddress>: unknown branch -> Weight

I have tried to include and exclude the  branch of 'Weight' in the phase space files, but the error did not go away.  I am using Gate v7.1.

Can someone give me some advice? Any help will be appreciated. Thanks!

Best,

Yuncheng  Zhong
