KeyError : 13

[Michele Lucente]

Hi,
I encountered a possible bug while running MadGraph and MadSpin with the "SM + Heavy N at NLO in QCD” model file (arXiv:1411.7305, arXiv:1602.06957).

Actually I am not aware of its nature, the only error message I have is "KeyError : 13".

I attach the debug.log file, the shell output is too long to be attached here but I can send separately if necessary.

Thank you,
Michele

Cheers,

Olivier
