[Bioperl-l] Please Help us - regarding TreeIO for Shared Distance

[jeevitesh at ibab.ac.in]

Hi Friends,

We need your valuable help in finding the SHARED PATH BETWEEN TWO NODES PAIR OF
A TREE.

The Distance method of TreeIO in Bioperl module gives the total distance.

But we NEED TO FIND THE SHARED(COMMON) DISTANCE BETWEEN TWO NODES as illustrated
in figure.

Suppose we have a tree
    A                C
     \              /
      \2          2/
       \__________/
       /    6     \
      /2          2\
     /              \
    B                D

The shared path between AB and AC is 2.
and for AC and BD the shared path is 6

Any comment on this will be greatly appreciated.

With Thanks & regards
jeevitesh
