<div dir="ltr"><div><div><div>Dear Wannier's owners and developers,<br></div>I posted my question more than a month ago. It was realted to running the code pw2wannier90.x for my system that is 4 carbon atom. Below was the error message:<br> -----------------<br> *** Reading nnkp <br> -----------------<br> <br> Checking info from wannier.nnkp file<br> <br> Something wrong! <br> rlatt(i,j) = 1.88808383092209 at(i,j)= 1.00000000000000 <br><br><br></div>At that time, Dr.Giovanni answered me by posting two links related to the same question. He also mentioned that my cell in .win file is different from that in nscf calculation. I checked all the possibilities that were suggested to generate such error. However, I have kept getting the same error message. Below is my input file for nscf calculation and .win file. Would you please help me with it? I am totally lost and new to this area. Any comment or feedback is greatly appreciated. Thanks in advance <br> <br><br></div><div><font size="4"><b>nscf file </b></font><br>&CONTROL<br> calculation = 'nscf',<br> verbosity = 'high',<br> pseudo_dir = '/share/apps/espresso/espresso-5.1/wannier90-1.2/pseudo/',<br> outdir = './',<br> prefix = '4clinear',<br> tstress = .false.,<br> tprnfor = .true.,<br>/<br>&SYSTEM<br> ibrav = 1,<br> a = 5.296375,<br> b = 10.000,<br> c = 10.000,<br> cosbc = 0.,<br> cosac = 0.,<br> cosab = 0.,<br> nat = 4,<br> ntyp = 1,<br> ecutwfc = 30.,<br> ecutrho = 240.,<br> nbnd = 8,<br> occupations = 'smearing',<br> smearing = 'cold',<br> degauss = 0.03,<br> nspin = 1,<br>/<br>&ELECTRONS<br> mixing_beta = 0.4,<br> diago_full_acc = .t.,<br> diagonalization = 'cg',<br> conv_thr = 1.D-10,<br>/<br>ATOMIC_SPECIES<br>C 12.0107 C.pbe-rrkjus.UPF<br>ATOMIC_POSITIONS {angstrom}<br>C 0.018367612 0.000000000 0.000000000<br>C 1.469108353 0.000000000 0.000000000<br>C 2.666542920 0.000000000 0.000000000<br>C 4.117280996 0.000000000 0.000000000<br>K_POINTS {crystal}<br>6<br>0.00000000 0.00000000 0.00000000 1.00000000<br>0.16666667 0.00000000 0.00000000 1.00000000<br>0.33333333 0.00000000 0.00000000 1.00000000<br>0.50000000 0.00000000 0.00000000 1.00000000<br>0.66666667 0.00000000 0.00000000 1.00000000<br>0.83333333 0.00000000 0.00000000 1.00000000<br><br><font size="4"><b>.win file </b></font><br></div><div>num_bands = 8<br>num_wann = 3<br>num_iter = 100<br><br>dis_num_iter = 100<br>dis_win_max = 17.0<br>dis_froz_max = -2.2225<br><br>guiding_centres = .true.<br><br>mp_grid = 6 1 1<br><br>iprint = 2<br><br>num_dump_cycles = 100<br>num_print_cycles = 10<br><br>transport = true<br>transport_mode = bulk<br>one_dim_axis = x<br>dist_cutoff = 5.5<br>tran_win_min = -6.5<br>tran_win_max = 6.5<br>tran_energy_step = 0.01<br>fermi_energy = -1.06<br>dist_cutoff_mode = one_dim<br>translation_centre_frac = 0.0 0.0 0.0<br><br>bands_plot = true<br>bands_plot_format = gnuplot<br><br>begin kpoint_path<br>G 0.0 0.0 0.0 A 0.0 0.0 0.5<br>end kpoint_path<br><br>begin projections<br>random<br>end projections<br><br>begin unit_cell_cart<br>Ang<br>5.296375 0.00 0.00<br>0.000000 10.00 0.00<br>0.000000 0.00 10.00<br>end unit_cell_cart<br><br>Begin KPoints<br>0.00000000 0.00000000 0.00000000<br>0.16666667 0.00000000 0.00000000<br>0.33333333 0.00000000 0.00000000<br>0.50000000 0.00000000 0.00000000<br>0.66666667 0.00000000 0.00000000<br>0.83333333 0.00000000 0.00000000<br>End KPoints<br><br>begin atoms_cart<br>Ang<br>C 0.018367612 0.000000000 0.000000000<br>C 1.469108353 0.000000000 0.000000000<br>C 2.666542920 0.000000000 0.000000000<br>C 4.117280996 0.000000000 0.000000000<br>end atoms_cart<br><br><br><br clear="all"><div><div><div><br>-- <br><div><div dir="ltr"><span><font color="#888888">Zeina Al-Dolami<br>PhD Candidate<br>Microelectronics and Photonics Graduate Program <br>University of Arkansas<br>Fayetteville, AR 72701<br>Office: PHYS 244<br>Email: <a href="mailto:zaldolam@email.uark.edu" target="_blank">zaldolam@email.uark.edu</a><a href="mailto:cxm075@email.uark.edu" target="_blank"></a></font></span></div></div>
