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.

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=**** / 0.000000 0.000000 0.000000 -18.176 -18.014 -6.915 -5.899 -1.571 -1.571 -1.546 -1.546 4.547 5.693 6.616 9.569 0.000000 0.010497 0.000000 -18.174 -18.012 -6.913 -5.896 -1.579 -1.576 -1.554 -1.550 4.550 5.696 6.619 9.571 0.000000 0.020995 0.000000 -18.168 -18.006 -6.905 -5.889 -1.603 -1.589 -1.578 -1.564 4.558 5.704 6.626 9.578 0.000000 0.031492 0.000000 -18.158 -17.997 -6.893 -5.878 -1.643 -1.611 -1.618 -1.586 4.571 5.717 6.639 9.589 0.000000 0.041989 0.000000 ................... 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 Elie A. M.
