Dear abinit users,
I want to calculate physical properties of ternary
alloys AB1-xCx in the zinc-blende phase using
supercell. My question is how to construct the input
files ( Definition of the unit cell):
Here my input file (or Common Data Definition of the
unit cell)for A B0.25 C0.75 
acell       3*7.373
rprim     1.000     0.000     0.00
