Formatting Data for LEfSe error message

Hello everyone.
I got the following error while exciting the command formatting data for LEFSe:

Traceback (most recent call last):
File"/shed_tools/", line 435, in feats = numerical_values(feats,params[‘norm_v’])
File "/shed_tools/testtoolshed.
Can someone explain, please?
Thank you!

Hi -
It’s a bit hard to debug without additional information. Could you provide an example of your input (feel free to mask away sensitive data) as well as parameter choices, please? You can also reach me at
