Description

@itamarwe

I'm trying to visualize a co-folded structure, for example: ..(((...((((((..&.)))))).((((....)))))))
When trying to visualize the structure, I'm getting the following error:

# Plot structure from dotbracket notation
fvm.plot_rna(forgi.graph.bulge_graph.BulgeGraph.from_dotbracket('..(((...((((((..&.)))))).((((....)))))))'))
plt.show()

The error:

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)
Input In [38], in <cell line: 2>()

      3 plt.show()
