Any SLHA2 implement?

Hi,

MadGraph does not care if your UFO model is based on the SLHA1/SLHA2 format.
The only problem in the past, was that Pythia6 was only working for SLHA1.
Since now PY6 is not supported anymore this is not an issue.

By default, we do not do it, but you can edit the run_card and set the parameter
time_of_flight
to the value that you want and the information will be written inside the lhef file.
Such that any code reading that file can use that information.

Cheers,

Olivier

I load the UFO generated from SARAH and generate some processes, the param_card seems SLHA2 format. However the question https://answers.launchpad.net/mg5amcnlo/+question/277185 indicate MG5 only support SLHA1?
