[Pw_forum] Problem in band diagram

[Balaji V]

 Dear All,
   When i generated the band structure of tin oxide bands cross each
other.. if we see the energy values of the last two bands for both k points
( at which it cross)  below we can the energy values of 2 bands are
interchanged.. Why this happen in a band diagram..
it happens in 4 to 5 places like this...

What is the reason for this and how to rectify it?

(This is a part of bands.x output .dat file)
