susy particle naming compliance with SLHA2

Dear Gauthier,

What you need is probably the following command:
import command XXXXXX --modelname
In that case MG didn't play with the name of the particles and keeps the convention that you choose in your model.
But in both case, MG didn't modify the name of the particles following a mass spectrum.

Cheers,

Olivier

But MG, when renaming squarks by dl, dr, sl, sr,... doesn't take this into account so that I get for instance the fairly confusing interactions
