[Pw_forum] Wannier BandStructure

[Giovanni Pizzi]

Dear Tommaso,
for Wannier90-related questions, please use the dedicated mailing list 
as explained here:
http://www.wannier.org/forum.html

For your question, I suggest that you first check the most updated 
tutorial in
http://www.wannier.org/doc/tutorial.pdf
(should be example 11) together with the example files in the examples/ 
subfolder of the Wannier90 package.
This should probably help you solving your problem (most probably you 
just defined the kpoint_path block, but did not write anything in it - 
in case of doubt, see also the very exhaustive documentation 
http://www.wannier.org/doc/user_guide.pdf).
If you still encounter problems, please post any further question on the 
Wannier mailing list.

Best,
Giovanni
