Running example error: ValueError: max() arg is an empty sequence

[梅然]

Hi all,

I was running the example dataset and encountered the error message:

......

Tree building finished in 1 secs (284 total time).

Traceback (most recent call last):

  File "./taxcuration/tree_reroot.py", line 43, in <module>

    tree.reroot( strategy = args['s'], tf = args['f'], n = args['n']) # , name = args['name'] )

  File "/Users/RAN/Desktop/Oo/phylophlan/taxcuration/pyphlan.py", line 658, in reroot

    longest = max( nodes, key=lambda x:x.branch_length 

ValueError: max() arg is an empty sequence

The tree in output was empty. I have reinstalled dependancies, cleaned old data files and re-ran the command but still got the error. Dose anyone have idea on this bug?

Thanks in advance.

Hi Ran,

I noticed that you're running PhyloPhlAn on a Mac system. We developed
PhyloPhlAn on Linux system, can you try to run it on a Linux system?


Many thanks,
Francesco
