K_POINTS
 311
  -0.500  0.500  0.500  1
  -0.495  0.495  0.495  2
  -0.490  0.490  0.490  3
  -0.485  0.485  0.485  4
  -0.480  0.480  0.480  5

You should change the k point set as follows:
K_POINTS
 311
  -0.500  0.500  0.500  1
  -0.495  0.495  0.495  1
  -0.490  0.490  0.490  1
  -0.485  0.485  0.485  1
  -0.480  0.480  0.480  1

Dear All,
  I was trying to do a Band calculation, and I got a error message like this :
      from card_kpoints : error #         1
      error or end of file while reading tpiba k points
The inputs is :
 &control
     calculation = 'bands'
     restart_mode='from_scratch'
     prefix='BaNiAs',
     pseudo_dir = '/disk2/xgwan/Quantum-Espresso/espresso-4.0.3/pseudo/',
     outdir='/disk2/xgwan/tmp/'
     wf_collect=.true.
 /
 &system
     ibrav=7,
     celldm(1)=7.7702,
     celldm(3)=2.806,
     nat=10,
     ntyp=3,
     ecutwfc = 40.0
     occupations= 'tetrahedra'
 /
 &electrons
     diagonalization = 'cg'
     mixing_beta = 0.7
     conv_thr =  1.0d-6

I knew errors happened in the K_POINTS. And I have checked for many
times, but I could not find where is the error.Would someone point it
out for me ? Thanks a lot.
Have nice day!
