Description
Hi,
I have HepMC events with arbitrary weights (both positive and negative). Is there a way to make Delphes use this information? From what I can tell this is not contained in the root tree from Delphes.
regards,
Wojciech

Thanks for the HepMC file.
Here is a version that stores the event weights as Event.Weight:

Could you, please check if this version works for you?

We are now currently testing the code but for the time being everything looks ok.
Thank you very much for your help.

HepMCEvent branch with Weight parameter is in Delphes 3.0.8 now.
Normally, there should not be any problem to add the weights to the root tree as we're already doing this for the STDHEP events.
Could you, please send us an example of such events? A small HepMC file with ~10 events would be enough.
