Add two spaces before the 496 and run again.

Does the structure have inversion symmetry or is it a complex calculation ?

@Gerhard: I must say I have seen much worse here on this mailing list, and I
suspect Sunday may be a perfectly regular workday for her.

That said, there is something strange with this calculation, as people
more knowledgeable than me already noted. Did you change something
fundamental between calculations, or might two different jobs have
run in the same work directory ? It might help to see your case.in1
and/or case.struct as well.

This would be better that you send the whole file case.scf, not only
a part of it. This would help us to understand the problem.

my calculations show metallic.

According to these calculations the bottom of the conduction band crosses

the fermi level,The gap is located in Valance band.

 

You said to check case.in2. I  check the second  line of my case.in2: 


 

  -15.50  496.00   0.50 0.05  1   EMIN, NE, ESEPERMIN, ESEPER0, iqtlsave

 

There  is a space before the second  number .

Why my calculations show metallic???

 please help me

Boy you are boring, 
No one knows what you did in particular, so how can anyone answer ?
and not everyone likes to work for you at Sunday

Do what Laurence suggested:   Why do you have in the first cycle of your 
attached file 496 electrons and later only 96 ? Did you check that ?
