GW and lines in k-space for bandstructure?

Can anyone post files for a successful run of calculating bandstructure under GW?

I'm sure someone has succeeded, and there is zero documentation I can find about it. (

I can get GW to work with a mesh of kpoints, but not a line for bandstructure.

Thanks!

If I am not wrong, obtaining a band structure from a density of states (DOS) calculation using GW potentials should be very much the same as using PAW or USPP potentials.

Is your structure optimized already?
Are you having difficualties obtaining the DOSCAR?

No, it's not a simple thing apparently. It gives errors about the k-points if you use high symmetry lines instead of a mesh. The only discussion I can find is at http://www.quantumquibbles.com/blog/?p=156#comments but no one in the comments seems to be able to get the results there
