Handoff to Qiime1 and phyloseq

Hi All,

I’m trying to find the best way to combine analyses generated in Qiime2 with some functionalities from Qiime1 and Phyloseq. for than, I need the taxonomy table exported. Is there an easy way, like what’s present for the biom table and phylogenetic trees, to do so (in a way that conforms with the taxonomy table format in Qiime1) ?


Hi @Gil_Sharon! You can export your taxonomy (or any Artifact for that matter) by running qiime tools export:

# An example, using some test data I have hanging out on my laptop!
$ qiime tools export ~/moving-pictures/taxonomy.qza --output-dir ~/Desktop/taxa-data
$ cat ~/Desktop/taxa-data/taxonomy.tsv

Depending on where you want to use this TSV table, you might need to remove the header row (e.g. QIIME 1, phyloseq)

Also, if you are interested in annotating a BIOM table with these data, you could export the FeatureTable, in addition to the data exported above, and use the biom add-metadata command to annotate the BIOM table.

Good luck, keep us posted! :t_rex:

Thanks, @thermokarst!

I suppose the feature table also has the sequence for each of the amplicons?

Never mind - got it (tutorials are a bit convoluted, but very very good, thanks! )

Alright @Gil_Sharon! If you have thoughts on how to structure the tutorials, feel free to open a new thread, we would love to get your input! If you haven’t seen this already, please check out the “Getting Started” guide - this is our suggested “flow” for getting to know QIIME 2! Thanks!
