visualizing protein families based on structure-pairwise similarity

Question

[Xylanaser]

hello

I'm looking for program like CLANS: a Java application for visualizing protein families based on pairwise similarity. Frickey T, Lupas A. Bioinformatics. 2004 Dec 12;20(18):3702-4

or something like that but based on pairwise structure alignments

OR please give me advice how to program it :)

cheers
