problem with gridpack

Hi Haneol,

1) https://twiki.cern.ch/twiki/bin/viewauth/CMS/QuickGuideMadGraph5aMCatNLO
is only for CMS user so I have no idea of what you are doing.

2) A lot of useful information is missing to your report. (for example, which version of MG5 you are using/ What is your cards?)
Please include the debug file indicated in the crash report. This will help (does not always contains all the information but this is a start).

From what I guess it looks like that you try to use MadSpin in order to have the helicity of the final state particle.
But I’m really confuse about this since
a) You are running at LO, so the helicity are already correct
b) You do not have tau in the final state which are typically the only particle where this information are relevant.

So my guess is that you are calling MadSpin when you do not need it, and I would advise to not do that.

Cheers,

Olivier
