Dear Wannier90 experts
                         I am doing LDA+DMFT calculation of cubic peroskite
system. I am using wien2wannier for generating Hamiltonian for DMFT
calculation. After running the wien2wannier interface I have genarated
Hamiltonian but I am not getting converged result. system is BaRuO3 in
cubic phase. My Ru t2g and eg bands are in the energy range 5 to -2 eV
which  I have taken for the projection but not getting the converged
result. please give some suggestion how I can get converged result. I am
givng win file and convergence of the output. Please help me...
