decay indices

[Nicolas Chalwatzis, MIPS]

Dear Netters,

I have the following questions:

- which paper describes the use of "decay indices" for the evaluation of the
  robustness of a phylogenetic tree (constructed from an alignment of 
  nucleotide sequences) ?

- what programs are available for the calculation of decay indices ?

Best wishes and many thanks in advance,

Nico Chalwatzis
