[BiO BB] Phylip distance matrix symmetry error

[Pedro Fernandes]

Hi Samantha

I may be missing the ccontext... but:

1) There may be a precision problem, any real number in a computer is rich in
decimal places that are not always seen, what is displayed is less precise, so:
subtract the numbers!

2) Some (!) Phylip rograms are known to be sensitive to invisible stuff on input
(insvisible being spaces, tabs, etc. So you may be evaluating somenthing that is
read with a wrong format.

3) Check carefully the origin and contents of all your files. Use Notepad++ for
example.

Good luck
Pedro
