Hi All,

There's probably a reason that this question hasn't been answered before on these forums (unless I just didn't search hard enough), but I would like to know which method (or methods) forms the basis of the clustering components in Pipeline Pilot, seeing as there're many out there.  Seems unfortunate I can't find out where this method came from, because I find it a very useful tool in my work.

I didn't manage to find anything after trawling through a few help files that seemed relevant. 

A scientific paper/review reference would be most helpful (especially an original one)!

Thanks in advance,

Ed.
