Well, I don't know what you really want to do with the .dnd file
from Clustal, but I saw so much errors with the pileup.figure tree that
I think I have to put a warning here :
The .dnd file generated by Clustal is NOT a phylogenetic tree.
This tree is only made using % identity derived from the pairwise
alignment and is used as a guide tree for the clustering alignement
(generating clusters by using the nearest neighbours in the tree).
We also found recently that we perhaps could use this tree to overweight
a sequence in the alignement (making a sequence drive the alignment).
We have to test it before documenting it, it's quite a hack ;-).
As said in the Clustal documentation, please use the Phylip
package if you are interested in tree.

Also, lot of details will appear in Nucleic Acid Research next week
(last issue of 1997).
