Dear all,
I have a quick question for using wannier90. I am interested in a molecular
system with only gamma point included in the pw.x calculation. For some
reason I cannot use kpoint{gamma}, instead I have to use kpoint = (0, 0,0).
The consequence is that the ground-state wave-function is not always real.
My question is, in this case should I use gamma_only=.true. in wannier90's
input. Thank you in advance for your response.
