 Dear QE users,

I am trying to calculate transmission conductance,but pwcond.x is
giving an error as shown


*Error in routine init_cond (1):     for numerical reasons  the 1st Layer
of a cell should be aligned with Z=0 plane*

I am taking transport in z-direction.I am attaching the input file of
pwcond.x and scf taht i uesd,Kindly  help me in this regard.
