Madgraph running with default setting

Hi,

If you run inside the same directory output, then the previous choice are kept (including the value for pythia/delphes).

If in your loop you always re-create the directory then in that case, then yes we do not have a user friendly way to enforce a different default for pythia/delphes. One option is to use a PLUGIN defining a new output mode where the only difference compare to the standard mode is to remove the Cards/pythia8_card.dat and Cards/delphes_card.dat /...
which will then turn those option by default then.

For having default for the run_card this is possible:
you can define parameter in the file
input/default_run_card_lo.dat

For the param_card this is also possible.
The best is typically to include in the UFO model a file
restrict_XXXXX.dat
which contains the exact benchmark that you want to use.
(see https://answers.launchpad.net/mg5amcnlo/+faq/2312)
and then instead of doing
import model YYYY
do
import model YYYY-XXXXX
(in top of having the default parameter, the computation will also be more optimised)

Cheers,

Olivier

But during each run, it asks for switches for pythia/delphes etc to be ON or OFF and also for editing the run_card and param_card. I do not need these switches and want to fix them to the default value 0 for every run. Is there a way to do that?

Hi Olivier,

  Thanks a lot for your response. Yes, I understand. I am running the loop every time in the same directory. So it is true that the switch that I choose the first time remains. However, during each run(generate_events), it does go to the user interface to ask, which switch to choose and it takes 60 seconds (to choose phythia/delphes switch) + 90 seconds (for editing param_card or run_card), to ultimately follow the default setting, if I do not manually choose the switch every time. Is there a way to avoid this user interface step?

Thanks and best regards,
Jayita

Hi Olivier,

It works. Thanks a lot for the solution.
