Shooting in the dark..

Can you try this bands.in version?

&BANDS

prefix = 'bscco',

outdir = './tmp',

filband = 'bscco.bands',

lsym = .true.,

nbnd = 160

/

The bands.x step usually does not expect K_POINTS in the input file.

Best,

Gabriel Vinicius I tried what you said, unfortunately it still got the same error. stopping ...

Error in routine bands (5010):

reading bands namelist

&BANDS

prefix = 'bscco',

outdir = './tmp',

filband = 'bscco.bands',

lsym = .true.,

nbnd = 160

/

Try a minimal test example, like the one below, to see how it goes

&BANDS

prefix = 'bscco'

/

If this works (it should), add the other parameters one by one to identify which one is causing the problem.

Gabriel Vinicius It seems the problem is lsym = .true.,

nbnd = 160, I tried without lsym =.true., it still have the same probleme. So the error might be in nbnd=160 and lsym =.true.,
