DADA2 execution halted (Error in table: attempt to make a table with >= 2^31 elements)

Thanks for your reply,

In summary, DADA2 create an unusually large table because of unremoved artifacts and low-quality base, resulting in the process suspension.

I will try the following methods to resolve the problem

  • Use q2-cutadapt and a reliable list to remove potential artifacts

  • Perform quality filtering and trimming before executing DADA2

I will update this post, if I find something important.

Thank you for your time and attention.
