O isotope cross section found for C12 off Element Nitrogen

Dear experts

Recently i am design an carbon pencil beam scanning model in GATE tools. However, an cross-section error happens . Here is the detail

The aim of this project is to establish an carbon pencil beam scanning model in gate simulation, so i designed an pencil beam first. The code runs well at first when i used GATE singel pencil beam commond setting, while when i change the beam setting in plan description&source property file the code will crash and remind "No isotope cross section found for C12 off Element Nitrogen ".

To avoid the code structure error, i change the ion typr from genericion(C-ion) to proton, the code runs well again. Then i use a lower energy in carbon(10MeV/U).Code also runs without error information. It realy confuse me, would u mind help me fix this problem? Thanks a lot for your kind help.Here is the code for check

Hello,

we are sorry but the question should be asked for GATE maintainers or you need to take directly one of Geant4 examples and compute this cross section.
