I seen to having the same issue uploading files into the Microbial Metabolomics portal as a few other users. I have my metadata, ASV count files, and raw metabolites files formatted per the examples for abundance tables (screenshot below, files attached). I get the green check mark when I upload all the files, but the screen will not advance when I click ‘proceed’.
Thank you for your response. I am still experiencing the same issue where the screen will not advance. Is there a certain browser or something else I should be using?
