Turning off MadSpin writing to mg5_configuration.txt

Asked by Hannes

Hi,

in MG5 2.6.5 MadSpin writes to the global mg5_configuration.txt. This causes an issue when MadGraph is installed on a read-only file system, as it is in our case. Is there a way to turn off this behavior?

Cheers,
Hannes

Hi Olivier,

thanks a lot for the quick patch!
For our information, is this something that will be included in future MG versions as well or is it just to patch on our side?

Cheers,
Hannes
