set non-zero aQGC value

Hello,

I would like to produce MadGraph samples with aQGC non-zero for the WZjj channel. For the SM production I use:

fcard = open('proc_card_mg5.dat','w')
if runArgs.runNumber in test:
    fcard.write("""
    import model sm-no_b_mass
    define p = g u c d s b u~ c~ d~ s~ b~
    define j = g u c d s u~ c~ d~ s~
    define mu = mu+ mu-
    define vl = ve vm vt ve~ vm~ vt~
    generate p p > e+ e- e+ ve j j QCD<=2
    output -f""")
    fcard.close()

How can I make the same configuration but set a QGC parameter, like FMO, to a non-zero value?

Thank you very much,
Iro
