my goal is to replicate metagenomic analyzes conducted on the 16s of bacteria with qiime2.
using the complete silva database with qiime I get % totally different from those provided, while if I repeat the analysis with the silva 16s database on kraken2 I can get practically identical results.
Surprised by this difference in values obtained using different databases, I want to create a database with only the 16s as the kraken2 one hoping to get similar results...
