You should use wf_collect= true for scf calculations. make sure you have g-vectors saved in your output. Follow this tutorial, http://www.yambo-code.org/wiki/index.php?title=First_steps:_a_walk_through_from_DFT_to_optical_properties HTH, Manu On Sat, Nov 17, 2018 at 5:48 AM foudil zaabar wrote:

dear all can any one help me to know how to get data.save for yambo code using qe-6.3 i want to calculat scf and nscf using qe-6.3, to get the data base ""prefix.save "" for yambo calculation but i have got only the wavefunction without the k points (eigenvalues) i used the following

other issue is that  celldm(3) is the ratio between c axis length and celldm(1), thus  you should consider values for celldm(3)  between 10./celldm(1) and 16/celldm(1). On 17/11/18 04:08, Yun Wang wrote: Dear Edmund, The (1x1x1) k-point mesh is not good enough to get the reliable data

Dear Prof. Mazari and colleagues, thank you again for your input. I have now run the calcs for a series of smearings (degauss=0.2, 0.1, 0.01, 0.001) and alpha_mix(1...4) from 0.7 down to 0.0001) but there does not seem to be a trend emerging. If you take a look at the attached plot it seems that
