Hi guys,

Is this linked to a new version of Delphes which needs one additional input file (and therefore incompatible with MG?)

Actually would not be easier, if you create a Delphes Team inside Launchpad? Such that I do not have to copy-paste such kind of bug?
(just have to assign the Delphes Team to the bug/question).

Cheers,

Olivier

By opening the other bug, I suceed to reach this page.
So any news about this?

I ask since I face the problem myself and that it probably means that it is impossible to use Delphes from MG for the moment.

Would it be possible to revert the version of Delphes downloaded by MG?

Cheers,

Olivier

Hi Olivier,

Could you make sure that the following Delphes condfiguration files are used in MG5?

examples/delphes_card_CMS.tcl
examples/delphes_card_ATLAS.tcl

NOT the following ones:

examples/delphes_card_CMS_PileUp.tcl
examples/delphes_card_ATLAS_PileUp.tcl

[olivier]

Hi Pavel,

Ok Indeed the default card that MG was using was the examples/delphes_card_CMS_PileUp.tcl
So this is on your side, I will change the default card used in MG.

Thanks,

Olivier.

PS: For all the people that I redirect to this thread one simple fix is to do:
cp Template/Common/Cards/delphes_card_CMS.dat Template/Common/Cards/delphes_card_default.dat
