[Gate-users] problem with random number seed?

[hediye acun]

Hello All,
I have Gate "develop" version and at the same time geant4.10.1.0 and root_v5.34.32 on the GPU. My operating system is Linux Mint 17.2 . 
I am triying to simulate a linac head to get Phase Space of photons. Just for an example I run Gate for a basic geometry which include only electron beam, target filter and Phase space plane inside a linac geometry. When I run Gate two or more times for same "number of primaries" I got the exactly the same Phase Space distributions (histogram of Ekine completely identical). But I am using "/gate/random/setEngineSeed auto" command and according to the documentation that should give me the different seed every time when I run it. I would expect some random differences between PhS's from different runs.
Does anyone have any idea about this issue? Thank you in advance.
