Hi @Ellenphant - does this post answer your question?

> Hi All, This might be a silly thing to ask (or a suggestion) - are Feature IDs (as in the name of an sOTU) assigned to deblured or DADAed data in a pseudorandom manner, or are they hashed from the sequence (and thus contain that information). they're definitely long enough to contain long sequences.. I'm just wondering if there's a way to use it as a sanity check when crossing platforms (and reporting data). Thanks! Gil

TLDR : yes, they have meaning, no, they aren't random.
