You can avoid it either by setting nosym=.true., or using calculation='bands' instead of nscf. </div>

<div>Dear,</div>
<div>I do the nscf calculation with the uniform k mesh. The k points is generated via kmesh.pl and the command is 'kmesh.pl 5 5 3'. And then the generated 75 k points is used to do nscf calculation. However, the number of k points in the output file is 99,
which is different with that in input file. How can I avoid this condition?</div>
