[Pw_forum] periodic cells for examples stm and 12

I was looking at input files in the examples using pwi2xsf.sh and
XCrySDen option for representation of several periodic unit cells. I do
not understand images for two inputs.
(1) STM example, AlAs110re.scf.in
One cell looks OK, but the option to see 2 cells along x gives only one
part of the initial cell attached, and then only this part repeats for
(2) example 12, AlwireH.scf.in
For this example, I do not understand an image for one cell. For pure
Al wire there are 4 chains in the image of one cell, and for wire with
an impurity there are 2 pure Al chains and 2 chains with H atoms. Then
cell for an impurity repeats along x in a way I am not able to connect
with periodic images of one wire with an impurity.
Thanks for help.
