ZeroDivisionError: float division by zero

[liufeibio]

Hi, @LKremer
I am trying to use CAFE_fig to visualize the results from CAFE, but I encountered some problems.
Here is my running: python3 ./CAFE_fig/CAFE_fig.py cafe_result.cafe -c asc=vL, da -pb 0.05 -pf 0.05 --dump test/ -g .pdf --count_all_expansions
And these are output:

Traceback (most recent call last):
File "./CAFE_fig/CAFE_fig.py", line 517, in
main(**vars(args))
File "./CAFE_fig/CAFE_fig.py", line 458, in main
c = CAFE_fig(report_cafe, families, clades, pb, pf, dump, gfx_output_format, count_all_expansions)
File "./CAFE_fig/CAFE_fig.py", line 86, in init
self.parse_tree()
File "./CAFE_fig/CAFE_fig.py", line 136, in parse_tree
self.parse_lambdas(line)
File "./CAFE_fig/CAFE_fig.py", line 209, in parse_lambdas
self.lambda_colors[i] = to_rgb(math.log(lambda_), min_l, max_l)
File "./CAFE_fig/CAFE_fig.py", line 62, in to_rgb
v = (v_abs - min_v) / (max_v - min_v) # scaled to a value between 0 and 1
ZeroDivisionError: float division by zero

Could you help with this? I appreciate your help. Thanks!

Thanks for your help with this. It solved this problem. But I encountered another problem:
Writing test/summary.pdf
Traceback (most recent call last):
File "./CAFE_fig/CAFE_fig.py", line 520, in
main(**vars(args))
File "./CAFE_fig/CAFE_fig.py", line 480, in main
p_value = family.tree.search_nodes(id=node_id)[0].pvalue
AttributeError: 'TreeNode' object has no attribute 'pvalue'
Could you help with this? I appreciate your help. Thanks a lot!

Did you resolve it? I come across the same problem now.

No, I haven't, it is still there.

Hi @liufeibio and @Hua-CM,
sorry for the late reply. I have two questions in order to narrow down the possible causes of the error.

1. Can you reproduce the example plot from the readme file (using example data and the command in the readme)?
2. if so, could you upload your input files here or send them to me via email (L.Kremer at dkfz.de)?
   Best, Lukas
