Hi Ahmed,

Hi sasha
i have got the problem !!!
The problem is that Delphes couldnt read the external hepml part ,although , its the latest version,
so one has to remove the hepml part then link it with delphes
thnks

Hi Ahmed,

thanks for letting me know.

This means that this is a bug in Delphes --
it should ignore
<hepml>
block
but eventually it does not do this.
You should let Delphes developers about this
problem and should not remove this block from .lhe file from CalcHEP.

<hepml> block is important one for MCDB
.lhe database at CERN
