Standard method to merge Taxonomy and Feature/ASV data

Hi Nicholas,

Thank you for the quick reply! Alright, then I can use that option. (I also made a mistake with the text to columns so now it looks good)

One question regarding the way QIIME2 merges objects:
e.g. with the following code:

qiime metadata tabulate \
--m-input-file table_transposed.qza \
--m-input-file taxonomy.qza \
--o-visualization merged.qzv

Does metadata tabulate merge on index/position, or does it merge on FeatureID?
I think it is FeatureID right? Because if I run the same command but NOT on the transposed table I get following error:

There was an issue with merging QIIME 2 Metadata:
Cannot merge because there are no IDs shared across metadata objects.
