[Wien] Spaghetti error

[Riyajul Islam]

Dear WIEN2k users,
I am running wien version 17.1 with operating system Centos7. I was
working on an orthorhombic structure with space group 51_Pmma. During
the bandstructure plot, I got the following error when I ran spaghetti
program

 SPAGH: Read band energy from case.output1
 number of k-points read in case.vector=         101
error in input: iprtf shall be <= 3
0.130u 0.011s 0:00.14 100.0% 0+0k 0+1416io 0pf+0w

Can anyone suggest me a solution for this issue?

Thanking you,
