SeqMotifFace

[jba4...@gmail.com]

I am trying to get the SeqMotifFace module to work, so I created a simple test script:


#########################################################################
#!/usr/bin/python

from ete2 import Tree, TreeStyle, TextFace, SeqMotifFace
from ete2.treeview.faces import add_face_to_node

tree = Tree( "(a,b);" )

# Basic tree style
ts = TreeStyle()
ts.show_leaf_name = True

my_motif = [[1,10,'[]', None, 10, 'red', 'red']]

def lof(node):

if node.is_leaf():
seqFace = SeqMotifFace(my_motif)
add_face_to_node(seqFace, node, 1, position="aligned")
ts.layout_fn = lof
#t.render("motifs.png", w=1200, dpi=300, tree_style=ts)
tree.show(tree_style = ts)
########################################################################

When I try to run this, I get the error:

Traceback (most recent call last):

What am I doing wrong?
