STOPMIX and Param-Card

Looks like your file is an SLHA2 file input.

So could you try the following:

cp -r models/mssm models/MYMSSM

then do
./bin/mg5_amc
import model MYMSSM
….

Like this MG5 will support the SLHA2 format.

Cheers,

Olivier

I have found in an earlier answered question, that I should easyly be able to convert the SLHA file to a param_card. (See: "Using SLHA-1 Spectrum file w/ Madgraph 5 pythia8 output" ) . In principle this works (I can generate a PARAM_CARD). But when i start MG5, i get an error message:
