Summary: PhyloXML cannot read node colors created by PhyloXML
Product: Biopython
Version: Not Applicable
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Main Distribution
AssignedTo: biopython-dev at biopython.org
ReportedBy: joelb at lanl.gov
Using a simple example file provided:
>>> tree = Phylo.read('bcl_2.xml','phyloxml')
>>> tree.clade[0].color = Phylo.PhyloXML.BranchColor(255,0,255)
>>> tree.clade[0].color
BranchColor(blue='255', green='0', red='255')
Phylo.write(tree,'colored.phyloxml','phyloxml')
1
>>> tree2=Phylo.read('colored.phyloxml','phyloxml')
Traceback (innermost last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python2.6/site-packages/Bio/Phylo/_io.py", line 57, in read
tree = tree_gen.next()
File "/usr/lib64/python2.6/site-packages/Bio/Phylo/_io.py", line 42, in parse
for tree in getattr(supported_formats[format], 'parse')(file):

in color
return PX.BranchColor(red, green, blue)

__init__
), "Color values must be integers between 0 and 255."
AssertionError: Color values must be integers between 0 and 255.
This is not a problem with an example file not written by biopython:
>>> tree = Phylo.parse('made_up.xml','phyloxml').next()
>>> tree.clade[0].color
BranchColor(blue='28', green='220', red='128')
Also, forester/archaeoptryx is able to correctly read colors written by
biopython.
