Bug Description
Hello Madgraph experts,
I am new to Madgraph, and i want generate some SM processes in NLO accuracy, for example the process
"q qbar -> z z -> mu- mu+ mu- mu+", so i did the following:
$ import mode loop_sm
$ generate p p > z z [QCD]
$ output testprcocess
$ launch -m
and have edited the madspin card, so that the z boson decays only to mu- mu+ pairs, but i get this error "log file attached"
Soft tests done for (Born) config 1
Failures: 31
Soft test 4 FAILED. Fraction of failures: 0.31
No collinear test for massive j_fks
Error detected in "launch auto -m"
write debug file /home/user/
If you need help with this issue please contact us on https:/
aMCatNLOError : Some tests failed, run cannot continue.
Please check that widths of final state particles (e.g. top) have been set to 0 in the param_card.dat.
quit
INFO:
Could you please help me??!!
Thank You

Hi,
I cannot reproduce your bug with these commands..
Can you please upload the cards (run, param, proc and madspin) that you use for this process?
Cheers,
Marco
