"Sample names match (metadata vs. OTU table): No" issue

I have used the MicrobiomeAnalyst well with my biom and metadata files since two months ago. However, presumably after a recent update, there is an error message as follows: Sample names match (metadata vs. OTU table): No (please see the below image as well).
Could you please review this issue?
Thank you so much.


In most case, this is caused by the mismatched names or wrong format upload. Please double check whether the files are in the correct format and if the sample names are the same in metadata and OTU table.

If the problem still exist, please follow our post guideline our for further trouble shooting.

Hope this helps.
