Dear all


I would like to include Berry phase in calculation of wavefunction of
graphene but it seems I cannot to it by   lberry=.true.
     Error in routine iosys (1):
     Berry Phase/electric fields only for insulators!

is there any possibility to include geometry phase or Berry phase in
wavefunction when I calculate graphene wavefunction.

Best Regard,
