When publish paper, how to cite ATK software ?

[fangyongxinxi]

Dear,

when publish papers with ATK software, of course we have the copyright,

usually, we write the following things in paper:

 " ***** using the DFT calculation engine in ATK [ref]"

how to wirte the " ref"
is there any papers, or something, we should cite ?
I checked some papers in the publication list, did not find a good answer.


thanks
