[Pw_forum] STOP ERROR reading file header

[Eyvaz Isaev]

Dear Eli, 

First, are you familiar with Fortran? If not, please learn about formatted 
input/output. 


The stars mean you use more than 9999 k-points that seems to be quite 
unreasonable.  Use less k-points.

Bests,
Eyvaz.

Subject: [Pw_forum] STOP ERROR reading file header

 Dear All, I am doing calculations for the band structure of bilayer graphene in 
the presence of an electric field. I reached the stage where the .DAT file was 
produced. However when i executed the plotband.x common using 
/espresso-4.2/bin/plotband.x  and input"ed" the .DAT I got the error:
 
STOP ERROR reading file header.
 
When I checked the .DAT file I realized that the header is strange as it 
contains four stars (****) and looked like that:
 

&plot nbnd=  12, nks=**** /

...................
 
I tried to re-execute the bands.x command several times but in vain as the 4 
stars re-appeared everytime. Does anyone know why is this occuring and how to 
treat it?
 
Thanks
