Error in Lefse LDA Effect Size

I generated a new data.txt and successfully uploaded and formatted the data set. However, when running LDA Effect Size, I received the following traceback error:

Traceback (most recent call last):
File “/usr/local/bin/”, line 5, in
from lefse.lefse_run import lefse_run
File “/usr/local/lib/python2.7/dist-packages/lefse/”, line 4, in
from lefse.lefse import *
ImportError: No module named lefse

To be safe, I re-uploaded a .txt file that I successfully ran in the past and received the same traceback error. The last line, “ImportError: No module named lefse” makes me think that there was an issue with the command line itself rather than my file.

Please advise. Thank you.
