Question QGSP_BIC_HP 

Forum: Physics List
Date: 13 Apr, 2016
From: Honghu Song <Honghu Song>

Dear all: I am simulating neutron with the organic det(mainly C and H),with energy below 20MeV ,using physics list QGSP_BIC_HP.

Program can run normally and also a histo.root output. While the prompt gives messages like follows:

My question is : (1) Is this something I should worry? I see one reply indicating the relevant dataset is absent in G4, Is this right?
                            (2) If we can download data library from other source (IAEA) and link with G4? Any one has tried?
Thanks in advance!
Best Regards!
