 Dear all:
       I want calculate the DOS of the carbon nanotube with (5,5) structure.The pw.x runs well, but the dos.x tuns with problem. The input file for pw as follows:
-----------------------------------------------------
&control
    calculation='nscf',
    restart_mode='from_scratch',
    prefix='Ctube-nscf'
    pseudo_dir = '/home/wien2k/pw/pseudo/',
    outdir='/biology/wien2k/pwwork/Ctube/'
 /
 &system    
    ibrav = 6, celldm(1) =20, celldm(3)=0.2394284, nat=  20, ntyp= 1,
    ecutwfc = 40.0
 /
 &electrons
    mixing_beta = 0.7
    conv_thr =  1.0d-8
