Enquiry for lefse analysis

I have come across many papers using lefse for statistical analysis of NGS data. I have followed this tutorial for reference

I want to apply lefse in my analysis too. However, I did not succeed to format my OTU data to input it in lefse for analysis. OTU frequency table was analyzed through Qiime2.

Please do kindly help.

Hi H. Nakibapher Jones Shangpliang,

Please direct to hmp_small_aerobiosis.txt to see an example LEfSe input file. Additionally, would it be possible for you to provide your input sample/example data to look more into the issue?

Hello Shangpliang,

I tried to run Lefse in Galaxy using your data and it runs OK, the only issue is that id does not find any discriminant features in your data.
Let me know if you have any further questions.
