I have some doubts with the taxonomic results I am getting. At first taxonomical level, it seems the analysis has been done correctly (the unassigned % is not too big, aprox 10%).
However, when I go through deeper levels, even if the unassigned % remains the same, there is an assignation that is called K_bacteria, which comprises almost the 80-90% of the assignations, that does not give more information (I attach some pictures, so the problem can be better understood):.
The version of Qiime2 I am using is QIIME 2 Core - 2020.6 and it is installed in Oracle VM VirtualBox.
The analysis I have performed is based on the “Moving Pictures” tutorials, using DADA2.
The samples correspond to feces of patients and controls.
Don’t know if more information (exact commands or more pictures) is necessary in order to make easier to help me.
Thank you too much in advanced!
