I am conducting a GATE Monte Carlo simulation using a brachytherapy phase space source. I designed a brachytherapy source and utilized the phase space actor to generate a ROOT phase space source output. Now, I intend to use this source in a new simulation. However, when I call the source, I encounter the following message:

“The option ignore time is false, but no time was found in phsp.”

I would like to understand what the problem is. Thank you in advance for your valuable answers.
