[Genome] how to cite - urgent

[Borut Oblak]

Dear Sir!

We downloaded your
Human(hg18)/Chimp (panTro2) pairwise alignments
in axt format from your
http://hgdownload.cse.ucsc.edu/goldenPath/hg18/vsPanTro2/axtNet/
web page for our research.

Now we would like to cite you and the authors of the alignment in our 
article, but we do not know how. We also do not know who are the authors 
of the alignment. Please help us.

Best wishes,
Borut Oblak
