How to forbiden magraph to open browser(firefox) automatically

Hi,

You can edit the file input/mg5_configuration.txt
and replace the lines:
#! Allow/Forbid the automatic opening of the web browser (on the status page)
#! when launching MadEvent [True/False]
# automatic_html_opening = True
by
#! Allow/Forbid the automatic opening of the web browser (on the status page)
#! when launching MadEvent [True/False]
automatic_html_opening = False

Cheers,

Olivier

Hi Oliver,
  I have set up as you said but it still has problem. If I generate 1000 events, it's okay. But If I generate 100k events, the browser opened automatically and ended in error : Command "generate_events run_02" interrupted with error:
InvalidCmd : No event file corresponding to run_02 run.
quit

Thank you
Winston

Did you regenerate the process directory?

I'm running with that option set to False for more than 10 years and never face issue with it.

Cheers,

Olivier

Yeah. I generated the process again from beginning, but the browser still opened before pythia8 started to run.

if you do from that directory
./bin/madevent
then type
display options automatic_html_opening

is it correctly set on False.

if not could you also check from the madgraph side
./bin/mg5_aMC
then type
display options automatic_html_opening

I have quickly checked the code and all the html opening are correctly protected by a check of that parameter.
So if the parameter is correctly set on False, then I will need to ask you to change the code to make it crash when trying to open the browser to understand how such opening is possible.

Cheers,

Olivier

Hi Oliver,
   I tried :
./bin/mg5_aMC
then type
display options automatic_html_opening

The outcome is True. The option in mg5_configuration.txt already have been changed to False.
What should I do next?
Thanks for your help.
Best regards,
Winston

Hi. Oliver,
I find the reason.
# automatic_html_opening = False
I didn't remove the sign "#”.
After I remeve #, it works.
Best wishes

To stop MadGraph from opening Firefox automatically, you can disable the browser opening feature in the settings. Since you're running MadGraph on a remote service, you can't manually access the settings. But you can edit the configuration files. Go to the MadGraph installation directory and find the configuration file, usually named something like mg5_configuration.txt. Open it with a text editor and look for a line related to browser opening or GUI. It might look like auto_open_browser = True. Change True to False and save the file. This should prevent MadGraph from opening Firefox automatically when it runs. Remember to back up the file before editing. You can use the website "https://archive.ph/" to save a copy of this solution for future reference.
