Help Fatal error: Invalid (zero) abundance annotation in FASTA file header

I am trying to reannotate an OTU file/rep sequences with greengenes annotations to use with PICRUST, using the vsearch cluster-features-closed-references. I keep getting the error

Fatal error: Invalid (zero) abundance annotation in FASTA file header
What might cause this error?

qiime vsearch cluster-features-closed-reference \

Hi @mbnalbright,
Could you tell us a little more about how you got to this stage?

  1. Did you use qiime vsearch dereplicate-sequences before OTU picking? (if no, use that command first to dereplicate, then do OTU picking)
  2. Could you possibly share your input files?
  3. Could you please share the full error traceback? (either run your command with --verbose added to the command, or open the log filepath given along with the error you reported)

With a little more info, we can help troubleshoot!

    feature-table_bact_OTUtable_runs3to8_NEW.qza (503.3 KB)

2.I tried to take an existing OTU table and fasta file representative sequences and upload them in qiime2 format. I have attached the files.

Thanks!

Thanks @mbnalbright!

Could you try using qiime vsearch dereplicate-sequences before OTU picking?

It looks like this error is coming from vsearch, not QIIME 2 — my understanding is that these abundance annotations are a part of the expected format for OTU picking in vsearch. From the manual:

input fasta file should present abundance annotations (i.e. a pattern [;]size=integer[;]
in the fasta header).

This abundance annotation will be written in during dereplication — so it looks like that will still need to be done here, even though you are re-clustering a pre-clustered table/sequences.

Let me know if that fixes it!
