distance models

[Rodo]

Hello,


I'm trying to test rate homogeneity between distances of severeal DNA
sequences using different models of nucleotide substitution, does anybody
knows any computer program where this can be done? This is, I'm searching 
a kind of Phyltest but with more models for calculate distances.
	A second possibility  is a program where I can calculate variance
and standard deviation using different models from Kimura and Jukes
cantor.


 thanks in advance
