[QE-users] qe-6-4: fs.x is not generating the file "prefix"_fs.bxsf

[Pacome NGUIMEYA]

Dear QE users,

I ran the scf and nscf calculation afterward I ran the fs.x program to
calculate the Fermi surface.
Everything worked except that the fs.x utility did not generate the file
"prefix"_fs.bxsf supposed
to contain the Fermi surface data.

What could have prevented fs.x from generating that file?

Below are my input files

*nscf input file*

                      prefix = 'TaAs',
