[Gate-users] DoseActor not recording any dose (empty 0's files)

[G Tom]

I am using GATE version 9.0 (March 2020), Geant4 version Name:
geant4-10-06-patch-02    (29-May-2020)
My phase space files that produce the source particles are from IAEAphsp
files and the headers look like this:

$RECORD_CONTENTS:
  1   // X is stored ?
  1   // Y is stored ?
  0   // Z is stored ?
  1   // U is stored ?
  1   // V is stored ?
  1   // W is stored ?
  0   // Weight is stored ?
  0   // Extra floats stored ?
  0   // Extra longs stored ?

Thanks

GT
