[Wien] super unit cell

Dear all,

For my case.struct (P lattice, 14 for the space group number), the 17th
atom (H) has two possible positions (0.0745, 0.5148, 0.4697/-0.1226,
0.5006, 0.3575), therefore, I would like to use
supercell to calculate the electronic properties for this crystal. My
question here is how to produce the supercell, i.e., how many cells in the
x, y and z directions? and how to change the 17th atom (H) coordinate
after the supercell has been created? I attach the original case.struct
with this email, any comments and suggestions are hightly appreciated!

Best wishes!
