Hello All,

I am able to do band structure calculations for bulk beta-Ga2O3 system and
it agrees well with the published results. Thanks for your help. Now I am
trying to use same method for 1-D Ga2O3 (nanowire) with supercell along
(010) direction with 54 atoms. I am getting following error. I have checked
my crystal structure with Xcrysden, I have attached (PNG format), looks
okay to me. Is it related to computer memory issue?
