Dear all,
After a SCF calculation of a crystal with the following cell parameters
* ibrav = 14,
celldm(1)=5.913520,celldm(2)=1.386316,celldm(3)=1.593551,
celldm(4)=0.084426,celldm(5)=0.313644,celldm(6)=0.268903
I performed a band calculation (restart_mode='from_scratch') using the
path bellow which has been generated by xcrysden.

.....
But in the output the path looks like this :
number of k points= 40
cart. coord. in units 2pi/alat
k( 1) = ( 0.5000000 -0.1395931 -0.1651425), wk =
0.0500000
k( 2) = ( 0.4500000 -0.1256338 -0.1486282), wk =
0.0500000
k( 3) = ( 0.4000000 -0.1116745 -0.1321140), wk =
0.0500000
k( 4) = ( 0.3500000 -0.0977152 -0.1155997), wk =
0.0500000
k( 5) = ( 0.3000000 -0.0837559 -0.0990855), wk =
0.0500000
k( 6) = ( 0.2500000 -0.0697965 -0.0825712), wk =
0.0500000
k( 7) = ( 0.2000000 -0.0558372 -0.0660570), wk =
0.0500000
k( 8) = ( 0.1500000 -0.0418779 -0.0495427), wk =
0.0500000
k( 9) = ( 0.1000000 -0.0279186 -0.0330285), wk =
0.0500000
k( 10) = ( 0.0500000 -0.0139593 -0.0165142), wk =
0.0500000
k( 11) = ( 0.0000000 0.0000000 0.0000000), wk =
0.0500000
k( 12) = ( 0.0000000 0.0534944 -0.0000050), wk =
0.0500000
k( 13) = ( 0.0000000 0.1069887 -0.0000101), wk =
0.0500000
.....
and like this
k = 0.5000-0.1396-0.1651 band energies (ev):
k = 0.4500-0.1256-0.1486 band energies (ev):
k = 0.4000-0.1117-0.1321 band energies (ev):
k = 0.3500-0.0977-0.1156 band energies (ev):
I compared the lattice and reciprocal lattice parameter in both the scf
and band outputs, and they are (obviously) exactly same.
So I'm just wondering what's going on here.
What did I do wrong?
Thank you,
?ric.
