Alpha and beta diversity error

Welcome to the forum @jose_gacia!

This error seems to suggest that you only have a single sample in your feature table. Is that correct?

If yes: don't use this method, since beta diversity is only meaningful if you have ≥ 2 samples. You could still run qiime diversity rarefy and qiime diversity alpha to estimate alpha diversity on that single sample if that is what you are after.

if no: run qiime feature-table summarize and please post the QZV here.

I hope that helps!
