Dear Prof. Gavin Abo
Thanks a lot for your kindness.
I will install wien2k_19.1 soon.
Kind regards
Sincerely yours
Tarek Hammad.

Also, consider using the latest WIEN2k version (19.2) because many spin orbit (SO) bugs can be seen to have been fixed since the 14.2 version that you are using:

http://susi.theochem.tuwien.ac.at/reg_user/updates/

The WIEN2k 19.2 version also has a user friendly init_so_lapw script that can be ran to automatically generate the case.inso making it less error prone then manually editing the case.inso by hand.

There is a bug fix [1] (or init_so_lapw.patch [2]) needed for WIEN2k 19.2 that fixes cases WITH inversion symmetry when for when init_so_lapw is ran several times.

Your TiC.inso file has 2 errors:

2 0.30 0.000 CONT             atom-number, E-param for RLO
0 0      number of atoms without SO, atomnumbers

The line for the RLO of the second atom is missing a blank and should read:
2  0.30 0.000 CONT             atom-number, E-param for RLO

In addition: It does not make sense to add a RLO for C-p states.
C is a very light element, has no semicore states and the C-2p valence
states are not really "relativistic".
I've never tried it, but it may even lead to a crash.

The error is exactly what it tells you:

The file /home/tarek/TiC/TiC.inso is not correct.

We cannot know what the error is without looking into the file.
