[Wien] end-of-file during read, unit 13 old_super.clm*

[Ravindran Ponniah]

Dear wien users,

I am trying to do structural relaxation for a spin polarized system for 
different volume. My job script look.

# Copy inpufiles to common scratch
cp $WORK/*.in* $RUN
cp $WORK/*.struct $RUN
cp $WORK/*.klist* $RUN

mv Mnsp1_0* $WORK

mv Mnsp1_15* $WORK

As the calculation was initialized with using Mnsp1_0.struct file, I am 
able to relax atom positions for Mnsp1_0.struct and able to get Mnsp1_0* 
without any problem. For the Mnsp1_15.struct case the job ran for the scf 
cycle and after the electronic minimization (scf convergence) it crashed
with the error message

The error file show that

It appears that old_super.clm* files were missing during the structural 
relaxation process. Do you think one should run

x dstart
x dstart -up
x dstart -dn

after the line cp Mnsp1_15.struct Mnsp1.struct 
in the job script?

Best regards
