[Pw_forum] bands_FS.x : Fortran runtime error

Hello,

I try to plot the Fermisurface of CaFe2As2 using the bands_FS.x routine.

I follow example02 of the PP-examples.



I receive the error message:

At line 353 of file bands_FS.f90 (unit = 5, file = 'stdin')
Fortran runtime error: Bad real number in item 1 of list input



I'm not really familiar with programming, especially not in Fortran.

Please can anybody explain this error.

Of course I found comunications about runtime-errors in bands_FS.x in this forum, but they cannot give me any hint whats wrong in my case.





In the attachment you can find the output of the bandstructure-calculation



my input_FS file looks like this:

The input file of the bandstructure-calculation is the following:
