at a first immediate look: --with-netdf=/home/dev/netcdf-4.0.1/ WRONG! --with-netcdf=/home/dev/netcdf-4.0.1/ RIGHT netdf is not netcdf !! please look at the compiling option of the confugure tool by ./configure -h to see how are the correct flags. and if you still find some problem, i

hi. a very small comment: 1) keep in mind that for this kind of materials if you want to perform a nice GW calculation is bettter to use pseudopotential with semicore states inside. 2) are yiou sure to be converged with the kpoint ? 3) and in particular with the nunmber of G vectors? i think
