Dear P. Blaha
We have problems in executing the program run_lapw -so for any structure.
Please help us. We used the steps suggested by the wien2k user's guide:
1) the case.struct was used in the mode RELA
2) init_lapw
3) run_lapw (the convergence was obtained after few iterations)
4) initso_lapw
5) run_lapw -so -ec 0.000001

The lapw0 and lapw1 are completed. After appears the following message:
forrtl: severe (59): list-directed I/O syntax error, unit 5, file case.inso.

What may be happened?

Thanks
A. T. Lino
