</span>Dear Meena,<br>
discriminating bands crossings from avoided crossings is not a trivial tasks.<br>
<br>
Three strategies are possible:<br>
1. sort the bands in order of energy (i.e. do nothing)<br>
2. use symmetry<br>
3. use overlap of wavefunctions at consecutive points<br>
<br>
bands.x can take all these thre eapproaches, if lsym and/or no_overlap are set<br>
to .true. or .false. See <<a href="http://www.quantum-espresso.org/wp-content/uploads/
Doc/INPUT_BANDS.html" rel="noreferrer" target="_blank">http://www.quantum-espresso.<wbr>org/wp-content/uploads/<br>
Doc/INPUT_BANDS.html</a>>.<br>
<br>
But in the end there is only one way to fix the problem for good: put more<br>
points in your path.<br>
