filter_outliers fails with a strange message of a missing file

Hi,
I am having trouble executing filter_outliers.filter_sequences. It throws the following error:

Traceback (most recent call last):
File "/hpcf/apps/python/install/2.7.13/lib/python2.7/site-packages/deenurp-0.0.0-py2.7.egg/deenurp/subcommands/filter_outliers.py", line 373, in filter_sequences
sequence_file, prefix, cpu=threads or wrap.CMALIGN_THREADS)

proc = subprocess.Popen(cmd, stdout=stdout, stderr=devnull)
File "/hpcf/apps/python/install/2.7.13/lib/python2.7/subprocess.py", line 390, in init

File "/hpcf/apps/python/install/2.7.13/lib/python2.7/subprocess.py", line 1024, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

Thus, it seems it is complaining about a missing file which puzzles me. I have supplied both a sequence fasta file to save filtered sequences and a taxa fasta file for the unfiltered sequences with taxa info. Both the filtered and the unfiltered fasta files are initially identical (before filtering) and I verified that both o the files do exist before entering the filter_outliers.filter_sequences step. Not sure what file is missing that the OS via subprocess is complaining about. Your help is appreciated especially if you have a detailed example on how to use filter_outliers and fill_lonely. Thanks much in advance.

I found the cause. I just forgot to load fasttree on the cluster! but the message does not indicate anything about fasttree. Thanks

Agreed, adding this Issue as part of next release. Thank you

Hi Chris,
Just a follow up on my earlier question regarding fill_lonely. I am trying to find examples of using fill_lonely on branches of a tree built using RAxML. Could you please be so kind to point me to where I can find such examples? An example snippet posted here could also help. Thanks in advance for your time.

I apologize for the slim documentation. We are working on it.

An example you can look at is in tests/fill-lonely. The sh script in that folder will run the fill_lonely example.
