Hi, everybody.

<BR>

I am working on making a java class for Phylogenetic tree generation, using Neighbor-joining method.

<BR>

While making the class, I read about additivity properties from the paper and books.

<BR>

My question is that if a given distance matrix doesn't hold that additivity property, than what shall we do and what can be done to avoid or alleviate that problem.

<BR>

I tried to get idea from other program sources, as far as I have been searching I could not grep any.

<BR>

<BR>Please help me. :)

<BR>

<BR>Thanks in advance 

<BR>Kim, Bong-Hyun from Korea
