Instead of 0 0 1 in case.inso, put the direction you want (1 1 0, or 1 1 1,
or ...). Usually this will break the symmetry of your cell, and symmetso
will create a new case.struct with this lower symmetry.

give me some

Just like the explanation line tells you: the first number is the number of
atoms, then followed by the number of these atoms in case.struct (see

By the way, mind your two RLO lines: isn't an increment needed there (just
as in case.in1) ?
