NLO generation
Dear all,
I would like to simulate NLO process using MadGraph5 version 3.4.1. I would like to shower using Pythia8 and use Delphes as a detector.
First thing, I cannot see any switch for the detector simulation. I was wondering if there is a way to use Delphes within the MadGraph5 interface or I should run it independently.
As for the error I am getting, I am just following the tutorial using SM and generating
generate p p > e+ ve [QCD]
but getting a "Configuration error" that I cannot understand. I point out that all LO generations work fine and with any model (also UFO written by myself).
generate
I paste here the output of the terminal and the log files.

If this is not what you need, please regenerate with the correct orders.
WARNING: Use of multiparticles is non-trivial for NLO process generation and depends on the orders included, the process considered, as well as the PDF set chosen. See appendix D of arXiv:1804.10017 [hep-ph] for some guidance.
