Hello,
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?
Many thanks!

Hi!
1 Convert a .csv file to .tsv and then to a biom file. This one you can import to Qiime as a feature table.
`biom convert -i feature-table.tsv -o feature-table.biom --table-type="OTU table" --to-hdf5`
```
qiime tools import \
--input-path feature-table.biom \
--type 'FeatureTable[Frequency]' \
--input-format BIOMV210Format \
--output-path feature-table.qza
```
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.
```
qiime tools import \
--type 'FeatureData[Taxonomy]' \
--input-path taxonomy.tsv \
--output-path taxonomy.qza
```
3 You also need a metadata file for this data.
If you have all three files, you are good to go and create a barplot.
