Issue with standalone_cpp subroutine
Dear Madgraph,
I have been using Madgraph (subroutine standalone_cpp) to get the squared matrix elements for a SUSY UFO model for dark matter. However I got an error.
I did this:
Import model MSSM_UFO2 --modelname
generate n1 n1 > h1 h1
output standalone_cpp nnhh
and, I got:
MG5_aMC>import model MSSM_UFO2/ --modelname
Kept definitions of multiparticles p / j / l+ / l- / vl / vl~ unchanged
Defined multiparticle all = g a nu1 nu2 nu3 nu1bar nu2bar nu3bar go sd1 sd2 sd3 sd4 sd5 sd6 su1 su2 su3 su4 su5 su6 sd1c sd2c sd3c sd4c sd5c sd6c su1c su2c su3c su4c su5c su6c d1 d2 d3 u1 u2 u3 d1bar d2bar d3bar u1bar u2bar u3bar sv1 sv2 sv3 se1 se2 se3 se4 se5 se6 h1 h2 ah2 hm2c z wmc sv1c sv2c sv3c se1c se2c se3c se4c se5c se6c hm2 wm n1 n2 n3 n4 c1bar c2bar e1 e2 e3 c1 c2 e1bar e2bar e3bar

str : Only support for SLHA blocks with 1 or 2 indices
Nonetheless, when I did the same but with output "standalone" only (no "_cpp") everything works well. It is also ok when I used without standalone subrutine.
I would very appreciate your help in fixing this error.
Best regards,
Javier.
