Band unfolding for supercells with additional atoms|

- Dear Developers,
Band unfolding is very useful tool for analysis of the band structure of surfaces with adsorbates. But, the supercell additionally contains atoms of the adsorbate, which were absent in the primitive reference cell, and it is unclear how to map extra atoms in supercell on to the reference cell.
If I naively add extra atoms (10,11,12,13) into the block
and map them onto nonexistent atom 2 in the reference cell, I get the following message:
Cannot assign atoms in the reference cell properly! Could be due to more than one same atom in the reference cell!
Check the input file, maybe the structure is highly disordered or you need to set the reference origin by yourself!
How to handle with the mapping in such situations?
Thanks in advance
