Dear All

I simulated and verified a linear accelerator with Gate (7.2). The program was divided in two parts for more calculation. In the second part of the program, Phase Space with root format which was located after flattening filter was used as a source. But when I run the program I got the below error

“GateSourcePhaseSpace.cc (l.200): No particle type defined in phase space file.”

I wonder if someone have any experience with this error and can help me in this issue?

I use Ubuntu 16.04, Gate (7.2), Geant 4.10.2 on cluster...

I do not have this problem when I use IAEA format for phase space but as MC user know the root format is more useful and even it can be edited too..

Best
