[Pw_forum] Error running bands.x / dos.x

[Sunny Gupta]

Hi

My name is Sunny and I was trying to calculate the matrix elements of
momentum operator using lp=.true. as well as the symmetry of bands using
lsym=.true.

My system is a MoS2 supercell with a single sulfur vacancy in -1 charge
state. I am able to successfully do the scf calculations but while either
running postprocessing bands.x or dos.x, I am getting this error.

      Error in routine checkallsym (2):
     not orthogonal operation

This error pops right at the start even before qe reads the pseudopotential
files. It will be great if anyone can help me in this!!

Thanks in advance.
