How to Cite Morph Server and CNS Script

I have found your Morph Server and CNS script very useful, particularly for providing a good visual aid for presentations and such. I am currently preparing some manuscripts for several protein crystal structures, which have two different conformational states. I was considering using your script to generate a morph of the two states, and creating an animated video of the conformational change to be included in the supplementary material of the paper. I was wondering if you had any requirements or wishes regarding the citation of your script. Obviously we would cite your work in the paper itself, but I was wondering if you had any other preferences for the inclusion of a citation in the supplementary material, such as putting a citation at the end of the animation. Any recommendation you could provide would be much appreciated.

Best to just cite
http://papers.gersteinlab.org/papers/molmovdb-update-nar/
http://papers.gersteinlab.org/papers/morphs-nar/
in the paper and end of suppl. material (if possible).
