Command "generate_events run_01" interrupted with error: Exception : too much decay at MG level. this can not be done for the moment

[Saumyen Kundu]

While running the MadGraph5, I got an error report that says,
"Command "generate_events run_01" interrupted with error:
Exception : too much decay at MG level. this can not be done for the moment"

[Olivier Mattelaer (olivier-mattelaer)]

Why do have MadSpin set to "ON" for this process?
Since you ask all the decay with the decay syntax, MadSpin sounds useless here.
So just do not ask for MadSpin and it should be working.

Note that MadSpin can add additional decay to process with some decay syntax but not for the process that you ask (this is the reason of the warning that you see).

Cheers,

Olivier

Thank you so much, Olivier for the help. Actually, I have just started to
learn MadGraph and all these. That's why this kind of mistakes.
Thank you once again for the advice.
