Error Message for File Format

Hi, I received the following error message for my OTU table while formatting. What does it mean? I thought I made an exact txt file for the LEfSe application.

Thank you!

Traceback (most recent call last):

File “/shed_tools/”, line 429, in

class_sl,subclass_sl,class_hierarchy = get_class_slices(zip(*cls.values()))


Hi -

Sorry for the late response! If you haven’t resolved this, would you mind sharing the input file? You can also reach me at if concerned about data safety.


Hi @sma
I am getting the same error while trying to do LFSe from the galaxy platform.
test1.txt (1.0 KB)

I have attached a test file. Please let me know what is causing that error so that I can edit my input file.
