[Wien] A problem with band structure calculations: lapw1c

Dear Prof Blaha


I'm doing some calculations on Fe-doped ZnS (cubic with SG 216) using Wien2k 17.1.

1- I set the k-mesh to 10x10x10 which correspond to 47 k-points.

2- The scf ended successfully.

3- Upon trying to plot the band structure I got the following error

forrtl: severe (24): end-of-file during read, unit 5, file /home/osama/osama.in1c

error: command   /home/osama/Wien2k171/lapw1c uplapw1.def   failed

this means it calls lapw1c instead of lapw1. Why this is happening since the calculations are in a complex mode?. in another words, why w2web does set the command line: x lapw1 -band -up instead of x lapw1c -band - up?


If the command x  lapw1c -band -up  is executed from the terminal everything run  without error.


Can you please clarify me this situation. Am I doing something wrong or it is a bug?.


Best wishes


Osama
