Tree render/show method bronken afte edit SeqMotifFace

[acpguedes]

I'm trying to draw a tree with SeqMotifFace to set build domains as face of each leaf.

Since I'm using Pandas, I have a dataframe like this:

ID	domain	start	end	evalue	fg	bg	w	h	shape
seq1	AMM	6	396	1.500000e-118	#bf443f	#bf433f	None	10	()
seq1	HisKA	469	534	4.000000e-21	#bf5f3f	#bf433f	None	10	()
seq2	AMM	37	427	2.000000e-110	#bf443f	#bf433f	None	10	()
seq2	PAS_9	506	600	2.100000e-05	#bf443f	#bf413f	None	10	()

I also have a tree for theses sequences.

So, I'm using a for loop to set the face of the sequences this way

for i in ( list(set(dom.ID)) ):  
    motifs=dom[dom.ID == i][['start', 'end', 'shape', 'w', 'h', 'fg', 'bg', 'domain']].values.tolist()  
    print (i, motifs, "\n")  
    seqface = SeqMotifFace(None, motifs=motifs)  
    (t & i).add_face(seqface, 0, 'aligned')

The print above turns:

Seq4 [[14, 405, '()', None, 10, '#bf443f', '#bf433f', 'AMM'], [457, 555, '()', None, 10, '#bf453f', '#bf513f', 'PAS'], [581, 688, '()', None, 10, '#bf6a3f', '#bf433f', 'HisKa']]
Seq5 [[8, 387, '()', None, 10, '#bf443f', '#bf433f', 'AMM'], [358, 445, '()', None, 10, '#bf463f', '#bf433f', 'SMC_ScpA']]

Exactly as required for motifs.

No error is returned in this loop, but...
When I try something like t.render("%%inline") or t.show I get this error

The tree is okay, if I just load the tree and try render or show it's been drawn nicely.I just got the error after insert motif face.

UPDATE:

add font size and color to motif name

Anyway didn't work

for i in t.get_leaf_names():
    motifs=dom[dom.ID == i][['start', 'end', 'shape', 'w', 'h', 'fg', 'bg', 'domain']].values.tolist()
    seq=str(f[i].seq)
    _ = []
    motifs2 = list()
    for m in motifs:
        _ = "arial|8|white|" + m[7]
        motifs2.append(m[0:7] +[_])
    print(motifs2)
    seqface = SeqMotifFace(seq, motifs=motifs2)
    (t & i).add_face(seqface, 0, 'aligned')

is it solved? otherwise leave the issue open so we can track all bugs for next code sprints...
