Bug Description
Dear experts,
I got the error "IndexError: no such group" [1] and the corresponding bug report [2] at the very end stage of
the gridpacks production. You can find the logs and the output gridpacks in https:/
The used cards and the documentation are placed in the following
repository: https:/
Given that the W boson decay is defined in the madspin file and the NLO
reweighting is applied over the proc_card processes, a change in the the
order of the reweighting and the decay steps through a patch is
needed as discussed in
https:/
this fact is related to the error.
Any help is welcome.
Thanks,
Pedro

The link that you give:https:/
does not speak about inverting the step (at least I failed that discussion)
But this does not seem to me that you can "simply" flip the two.
You will face a lot of problem when flipping them. The biggest of all is that MadSpin will need to evaluate matrix-element that we are not able to generate right now.
If something is going trough it is certainly not NLO accurate.
So I do not think that such strategy can work for NLO generation,
Cheers,
Olivier
