I have some abundance data generated from other tools in the form of .csv data.
They contain the taxa ids and their levels of abundance.
Is there a way to visualize these data as QIIME2 taxa bar plots, so I can combine these with my other data that were analyzed with QIIME2?
2 You need a taxonomy file. If you have it outside of Qiime, make sure that it looks like a .tsv file used in Qiime2 taxonomy artifact. To check, how it should be formated, you can open as an archive a taxonomy.qza file, produced earlier in Qiime2 and navigate to data/ directory inside. When the file properly formatted, import it to Qiime.
