Error in terminal about NeutronHP

Hi experts,
I see these errors in my terminal. but I got my results.
I want to know whether these errors affect my result or not.
my project is about radiation therapy.

The warning messages are just saying that there are no HP neutron data files for C-12 in G4NDL4.6 and so Geant4 is using the data files for natural carbon instead. Since natural carbon is 98.9% C-12 and 1.06% C-13, this will in all likelihood make very little difference in results.
