Hi
I was trying to do a GW calculation of SrTiO3 within the plasmon-pole approximation. However, I keep getting the error message :

m_bz_mesh.F90:1685:ERROR
Not able to found umklapp G0 vector among ***** vectors
Increase mg0sh such as k1-k2 = kf+G0, present value = 25
point1 = 5 1.25000000E-01 0.00000000E+00 0.00000000E+00
point2 = 3 0.00000000E+00 1.25000000E-01 -1.25000000E-01

Can somebody please help ?
