problem in decaying particles with madspin
Hi,
I have an issue with madspin. I have generated the process : p p > X [QCD] using one of the BSM models and it is launched twice one by applying the shower=ON, the other shower=OFF (run_01, run_02). I have then tried to decay the particle X which is unstable using the madspin. I have edited the madspin_card.dat to include the following decay: X > Y Y, Y > q q~, Y > w+ w-, w+ > b~ c, w- > mu- vm~
X, Y are just symbols for unstable particles Y is for higgs. I have written this decay with different syntax and I ran the madspin over the generated events for the two runs separately, but each time it gives the following error:
Command "decay_events run_02" interrupted with error:
InvalidCmd : No matrix elements generated, check overall coupling orders

I also, tried to change the spin mode several times, but unfortunately it is giving also the following error:
Command "decay_events run_02" interrupted with error:
ZeroResult : No Phase Space. Please check particle masses.

Could you kindly help me with this?
