Hi @ido1,

Welcome to the :qiime2: forum!

Do you mind sharing your shannon_vector.qza and Testmetadata.tsv files for me to examine? DM is fine if you'd prefer not to share them publicly. Thanks! :lizard:

shannon_vector.qza (52.5 KB)
Testmetadata.tsv (299 Bytes)

Hey @ido1 it seems as if your sampling depth is too deep, it only retains 2 samples; 98039 & W190020. I would suggest looking at your interactive feature table to determine a more appropriate sampling depth to retain more samples.

Check out this youtube video to help determine a sampling depth.
