Error in GM NLO generation with MadSpin
I am running MadGraph with Athena, the MadGraph version is 5.2.6.0.
I am trying to produce signal samples with the GM model with the following command:
define p = g u c d s u~ c~ d~ s~
define j = g u c d s u~ c~ d~ s~
define l+ = e+ mu+
define l- = e- mu-
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
import model GM_UFO_nlo
generate p p > H5p > w+ z j j $$ w+ w- z [QCD] @1
add process p p > H5p~ > w- z j j $$ w+ w- z [QCD] @2
The event generation works without problem, the error occurs when trying to decay the W/Z bosons with MadSpin:

What is strange is that when I run a local copy of Madspin on the events.lhe I runs without problem, so I am not sure why the problem only occurs in Athena. Do you have any idea why MadSpin seems to have problems loading the Model and decaying the W and Z bosons?
