Duplicates in my collapsed table

Hi Again!

I have collapsed my features table at level 6, that is genus. Ideally it must have all unique genera.
But the table I have, has duplicates.
For eg: let say genus “Prevotella”. I have this genus with different abundance values for each sample.
I also have “[Prevotella]”, in square brackets.it also has some values for each sample.

How is it possible?
Genus is same but still it is REPEATING.


Hi @Nisha,
This is not really a duplicate, as described below. This is a feature of the reference taxonomy that you are using.

Square brackets are official NCBI taxonomic nomenclature, indicating known misclassifications in the reference taxonomy. See here for details:
