error with dada2 - paired end sequences 2x250 bp

Hi @annsantos!

@annsantos

Error in isBimeraDenovoTable(unqs[[i]], …, verbose = verbose) :
Input must be a valid sequence table.
Calls: removeBimeraDenovo -> isBimeraDenovoTable

The error message is a bit confusing, but basically we see this message when DADA2 is unable to join any reads. Can you please provide the command you ran, and some more info about the target amplicon, region, primers, etc?
