I used this tutorial but I didn't understand what is level in this command:
qiime taxa collapse
--i-table table.qza
--i-taxonomy taxonomy.qza
--p-level 6 \ # or whatever level of taxonomy you want
--output-dir taxtable/
also after I did all the steps I got a file with just 37 rows while in table.qza or taxonomy.qza file there are more than 100 rows.
sorry if I am asking a simple question.
thank you
