Dear users,
I am calculating the phonon  spectrum of a bct structure. When I calculate 
the force constant file with q2r.x program, it comes out to be the same 
with zasr=.true. and zasr=.false. It should actually be different in the 
two cases. Where do you think the problem is arising? 

I calculated the force constants for gaas which is given as the examples 
in pwscf and with the same program q2r.x, the force constants are 
different with zasr=.true. and zasr=.false. i.e. there is no problem with 
the program as such.
