The problem is appearing because you have an empty $SCRATCH variable.

During userconfig_lapw, it is recommended to set SCRATCH either to a local scratch directory or to "./" . With this setting opticpara works.

However, you set it to " " (blank), and this causes the problem in opticpara, because opticpara appends to the SCRATCH variable a "/" (to fix the problem if somebody sets SCRATCH to eg. /tmp ; i.e. no "/" at the end) and this gives with your SCRATCH setting a "/case.mme"; which does not exist and cannot be accessed since it is in the root filesystem.

2 possible solutions:
a) edit your .bashrc file and set SCRATCH to "./"

b) edit opticpara_lapw and search for:

set scratch=`echo $SCRATCH | sed -e 's/\/$//'`/

remove the last "/" in this line.

Are you using the latest version of WIEN2k ? Opticpara was fixed some time ago.

If yes, please edit $WIENROOT/opticpara_lapw   and insert in the first line    -xf  (instead of -f) and rerun. Capture the output and send it to my private email together with your optic_1.def file.

Somehow it exchanges "case" to "/Case"

    Sir,
    Greetings!
    I am trying to calculate optical properties of a semiconducting
    material with hf potentials. After running scf cycles by hf
    potential, I generated a new k-mesh with the given procedure in user
    guide. Then I run "x lapw2 -fermi -hf -p" in the terminal. Which was
    followed by editing .inop file. Then I am trying to run "x optic -c
    -hf -p". And encountered by following errors:

    ________________________________________________________
