Hi Shaofeng,

feff, because I suppose you stacked in this moment of paths' calculations, is not suitable for partial occupancy.
There are already few discussions and tutorial about it (see below) - try to find something about doping. In principle the partial occupancy and doping can be in the same way calculated.
I do not know what you want to do, but my first suggestion would be - calculate FEFF paths with full occupation, and later in Artemis change the parameter N  (no. of degeneracy) to desired and for desired paths.

you can have a look also here

Hi Bruce,
 
I want to use a crystal structure file to calculate the path. But the software remind me it can not use crystal data whick has sites of partial occupancy. How can I solve this problem. See the file in attachment.
