[Pw_forum] scf convergence for 1-d insulator

Hello all,

I am trying to do scf calculations on 1-D polymer chain, but my scf 
calculations are converging. I have tried varying the mixing_beta and 
mixing_mode as suggested on many of the pw forum. I am wondering if 
someone have any insight on what I am doing wrong.

I am attaching my pw.in and pw.out files. Also I am attaching snapshot 
of my molecule as generated by XCrySden.

Thanks a lot,
