'GEOMETRY wrong or EMAX_SPLINE too small': can anyone help me to solve?

[Matthias Krack]

You have specified atoms with coordinates for equivalent positions by 
symmetry due to the applied PBC, e.g.
Si    0.000000    0.000000    0.000000
and
Si   10.861400   10.861400   10.861400
Remove all atoms redundant by symmetry.
