Dear MadGraph experts, I generated a LO sample with the SMEFTatNLO model: p p > l+ l- j j QCD=0 NP=0. I would like to reweight it into a NLO sample, so I modified the reweight_card into: change mode NLO change process p p > l+ l- j j QCD=0 NP=0 [QCD] launch The reweighting procedure is interrupted with the error Command "generate_events run_02" interrupted with error: KeyError : ((1, 5), (-13, 1, 5, 13)) Please report this bug on https://bugs.launchpad.net/mg5amcnlo More information is found in '/home/matteo/Scrivania/MG5_aMC_v3_1_0/bin/pp_Z_lljj_EW/smdir_lljj/run_02_tag_1_debug.log'. Please attach this file to your report. Can you help me understand what's wrong? Another question: once the events will be reweighted, they won't be physical unless I don't shower them, am I right?
