OUT ID not recognizable

[foxyg]

I imported some already split fastq files to a qza file successfully.
qiime feature-table summarize command was successful too.
After exported the biom table, and converted to a text file. The OTU IDs are some thing like this
b0aa1d99cf1a9f8bfe1b72599939d3f6
8a70768226ec08fe1f125af8032689a1

Did I do something wrong?

Thanks

Hey there @foxyg!

Did I do something wrong?

Nope! How did you create your feature table? If you used DADA2 or Deblur, those methods both hash the sequence as the feature ID by default:

  --p-hashed-feature-ids / --p-no-hashed-feature-ids
                                  If true, the feature ids in the resulting
                                  table will be presented as hashes of the
                                  sequences defining each feature. The hash
                                  will always be the same for the same
                                  sequence so this allows feature tables to be
                                  merged across runs of this method. You
                                  should only merge tables if the exact same
                                  parameters are used for each run.  [default:
                                  True]

Hope that helps!
