Help in calculating interclade distances

[Tulio de Oliveira]

Hello,
I would like some help in how to calculate inter- and intra- clade
distances between species used to generate a phylogenetic tree.

I had read that it is possible to perform that task using Clustalw and
SYSTAT, but I could not calculate the distances between the sequences.

Thank for any help
Tulio
