"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
quoted :GAP may be too large." [

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 wrong here?
