Creating MadGraph 5 model folders

[chrispb]

I used SoftSUSY 3.1.7 to create a spectrum that I'd now like to input into MadGraph 5 to compute cross sections with. However, the MadGraph calc that I used to use (on their webpage) is outputting me a param_card.dat file, which MG5 no longer appears to use as an input in the model folder. I want to turn this model (which is just MSSM at a specific point in parameter space, RG evolved) into a MG-compatible model folder without inputting each and every number by hand. Does anyone have some advice as to how I could go about doing this, or at least making MG5 play nicely with the param_card.dat file? MG4 requires g77, which seems to not be compatible with the latest version of gcc; otherwise I'd just run that instead. Thanks!

Hi chrispb, I am one of the MadGraph authors. You use param_cards in MG5 just as in MG4: Generate the process you are interested in, put the card in the Cards directory (or if you do it online, just upload the card), and run. Note that you need v. 1.4.x in order to use an SLHAI-compatible card with the default UFO mssm model.
