[Pw_forum] write a xsf file using pwi2xsf.sh

[dt378 at bath.ac.uk]

I have just started to use Espresso so I apologise if my question is a  
bit silly.
I would like to convert my input file in a xsf format but I can't.

This is the error it punch out:
"
chpc-aw7:zns davidetiana$ ~/espresso-4.3.2/pwtools/pwi2xsf.sh zns1.in
At line 426 of file pwi2xsf.f
Fortran runtime error: End of file
"
where am I wrong?
Thank a lot
