Dendropy looks for DNA alphabet when I use Protein.get

[taua...@gmail.com]

Hi all,

I am starting to use dendropy now. I have a very simple script in which I want to convert a Nexus dataset into a Phylip dataset:

import dendropy

import sys

concat = dendropy.ProteinCharacterMatrix.get(path=sys.argv[1], schema="nexus")

concat.write(path="teste.phy", schema="phylip")

But it returns an error saying that it cannot recognize the first amino acid because it is not in the DNA alphabet (of course).

dendropy.dataio.nexusreader.InvalidCharacterStateSymbolError: Error parsing data source '46taxa_concatenated.nex' on line 7 at column 14: Unrecognized character state symbol for state alphabet 'DNA' (DnaStateAlphabet) : 'L'

Anyone came across this issue before? Just installed dendropy, so I am using the latest version 4.2.0

Thank you!

Tauana
