Many Thanks for your detailed explanations. It was too great help for me. As I understand the basis sets must be after the atoms but I do not understand that I must put them in a separate part in the $DATA group or inside the XYZ (Z-matrix) part.

For instance :
which is correct:
------
$DATA
Ge
basis set

Si
basis set

Si 0.0 0.0 0.0
Ge 0.0 0.0 1.4
-------
or
-------
$DATA  
Si 0.0 0.0 0.0
basis set

Ge 0.0 0.0 1.4
basis set
-------
Best Wishes

>without blank lines between atoms. Don't forget to add $END in the end of the group. If some atoms have no ECPs, the corresponding lines look like
