I would like to know if I QIIME2 (like QIIME1’s taxonomy plots) can reveal the total relative abundance of the taxa (at user specified taxonomic levels); so that one could say, for example, Firmicutes and Actinobacteria were the most abundant phyla (relative abundance: 55.6% and 30.3%, respectively). In QIIME1’s taxonomy plots, this information can be got from the plots themselves (by mousing over on the plots or visualizing the taxonomy table).
@Nicholas_Bokulich thanks for your reply. The information I am looking for in QIIME2 would be like the one found here in the column labelled total (where you have count and %).
so use qiime taxa collapse and then qiime feature-table relative-frequency to convert to a relative frequency table. See the help documentation for more details.
