I have recived from a collaborator working with phyloseq a taxa data, where each taxonomic level is set up in a different column. I have used CONCAT command in excel to transform the table to the qiime format where all taxonomy level orgnaised in one string (head of table):
However, I do get an error while trying to import as qza (following transforming the txt. to biom.):
An unexpected error has occurred:
'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte
See above for debug info.
