Dear Qiime2 community,
With the l advent if greengenes 2, I thought I'd reanalyse my data with the new database. However, when I exported my data from Qiime2 to R, I ran into a predicament. My ASV table had the normal "4f9070b5d72c4cada7a60e06269fc149" format of classification. However, my taxonomy table was totally different with formats such as "MJ006-1-barcode41-umi149015bins-ubs-3" or "JN873915".
I think this disparity between the two tables is what's causing my phyloseq object error:
Error in validObject(.Object) : invalid class “phyloseq” object:
Component taxa/OTU names do not match.
Taxa indices are critical to analysis.
Try taxa_names()
I have attached screenshots of the tables below, please let me know if you have any advice!
Kind regards,
Johann
