I have looked at GRAS's examples for reverse monte carlo and it looks that I just can use the gps file data for defining the external source as follows:

/gps/ene/type Arb

/gps/hist/type arb

/gps/hist/point 1.000e-03 9.990e-01

/gps/hist/point 1.585e-03 9.984e-01

/gps/hist/point 2.512e-03 9.975e-01

/gps/hist/point 3.981e-03 9.960e-01

/gps/hist/point 6.310e-03 9.937e-01

/gps/hist/point 1.000e-02 9.900e-01

/gps/hist/point 1.585e-02 9.843e-01

/gps/hist/point 2.512e-02 9.752e-01

/gps/hist/point 3.981e-02 9.610e-01

# etc

/gras/analysis/adjoint/addUserDefinedPrimSpectrum e- 1. 1/cm2 Arb

/adjoint/DefineSphericalExtSource 0.000e+00 0.000e+00 0.000e+00 5.000e+00 cm

/adjoint/SetExtSourceEmax 1.000e+01 MeV

where the data is just differential fluence. So I could reuse the gps file from the forward simulation pretty much.

It would be great somebody familiar with GRAS adjoint commands could confirm. Thank you, Sveta
