Bug Description
Dear developers,
I´m facing a problem while generating p p > e- e+ mu- vm~ j j QED<=4 (QCD contribution). When I'm trying to reweight these events with this process p p > e- e+ mu- vm~ j j QCD=0 QED<=6 (pure electroweak) the error is this one:
INFO: starts to compute weight for events with the following modification to the param_card:

and the reweighting card is this:
change process p p > e+ e- mu- vm~ j j QCD=0 QED<=6
change helicity False
launch --rwgt_name=SM
/afs/cern.
Is there any way to do the reweighting?
Thanks in advance,

Hi,
This actually makes a lot sense since you do not have gluon final state for you re-weighting definition. So indeed you do not have any matrix-element with which to re-weight and therefore this lead to a crash.
Now I guess that in this particular case, the correct behavior is to set the weight of all those events to zero. I do not want to have this as the default behavior since this is the sign of a bug in 99% of the case. So I will add a flag in 2.6.7 in order to allow to set the weight to 0.
the way to set the flag would be finalstate True
change allow_missing_
Cheers,
Olivier
