Maybe okay? "Next to :GAP in the scf file there is a warning: if you use a proper k-mesh. One always has to check this :GAP value and compare it vs. a detailed bandstructure plot, identifying the position of VBM and CBM. If the scf k-mesh is course or does not contain Gamma (shifted mesh), the

Dear List, I compiled the results of a complex structure with PBE+SO. Results look okay to me what about I am worried is: When I do grep :GAP *.scf on terminal then it shows band gap ~1.01 eV. When I see at the plots then it shows band gap ~0.7eV at Gamma point. Could you please tell me whats w
