[Computational-biology] Betweenness Calculation

[mckenzie.tobias from gmail.com]

Hi,

I'm doing a project on residue networks and I have to calculate
betweenness of the residues. However I have to use a slightly
different betweenness definition. I don't have to use a all-pairs
shortest path approach. In other words I have to calculate the
shortest paths using some destination nodes, ie from node 1 to node t,
from node 2 to node t etc..

I don't have an idea on how to do that. Can you help me?

Thanks.
Tobias
