[Pw_forum] Invalid lattice parameters error

[Vahid Askarpour]

Dear forum members,   

The unit cell I'm using is triclinic (a=9.127 angstrom, b=5.519 angstrom, c=7.310 angstrom, alpha=89.99, beta=89.97, gamma=53.22). From the INPUT_PW file, I have set up the following input file but upon running, I get the error message [ from  iosys  : error #      1       invalid lattice parameters ( celldm or a ) : ]
