[Pw_forum] QE & Xcrysden

Dear Q.E. & Xcrysden
I am working on the various phase transitions of GaAs. I am trying to
contact these structures. I ahve managed to construct the ZB and RS
structures with success. I am using Xcrysden with Quantum Espresso.
When i try to view the CsCl-GaAs structure,  I only see the Ga atoms
and with no As atoms in the matrix. Can someone show me please where I
am going wrong
 my input file is this
 &control
   prefix='GaAs',
   pseudo_dir='/home/physics/Desktop/espresso-4.0.5/pseudo'
   outdir = './tmp',
 /
 &system
   ibrav=  3, celldm(1) =10.2, nat=  2, ntyp= 2,
   ecutwfc = 12.0,
 /
 &electrons
 /
ATOMIC_SPECIES
 Ga  69.723  Ga.pbe-nsp-van.UPF
 As  74.9216 As.pbe-n-van.UPF
ATOMIC_POSITIONS
 Ga 0.00 0.00 0.00
 As 0.50 0.50 0.50
K_POINTS {automatic}

Thanks
