An error in lefse v1.1.2

[liu-congcong]

Hi, thank you for developing the lefse.
An error may be encountered, when run "lefse_plot_res.py" as follows:

lefse_plot_res.py --feature_font_size 8 --format pdf --class_legend_font_size 8 lefse.output lefse.pdf

File "lefse_plot_res.py", line 102, in plot_histo_hor
if len(rr) > params['max_feature_len']: rr = rr[:params['max_feature_len']/2-2]+" [..]"+rr[-params['max_feature_len']/2+2:]
TypeError: slice indices must be integers or None or have an index method

It should be
"if len(rr) > params['max_feature_len']: rr = rr[:int(params['max_feature_len']/2-2)]+" [..]"+rr[int(-params['max_feature_len']/2+2):]"

I'm afraid you shouldn't change the codes, it'll cause an incorrect result.

I ran into this similar problem and like you, originally changed the code. However, we also thought this might result in incorrect plotting of the results. We added the option --max_feature_len and this helped (tried out setting around 100 as default is 60). Hope this helps someone!
