You can put in
i) the structure manually (w2web),
ii) you can use a modified xyz file (see UG xyz2struct)
iii) you can use cif2struct (see UG), either with a cif-file
or a case.txt file (this will convert a
special text file, not a cif file!!)
partial occupancies:
Fact is, that one position in space can only be occupied by ONE atom.
How you model your disorder/partial occupancy depends on you.
Most convenient is supercell, but you can generate atomic positions also
yourself and put them into an xyz file.
However, note: a "cluster of atoms" ???? We use periodic boundary conditions....
