Hello,
I am trying to run DADA2. My run completes, but only outputs (1) file: table.qza
I was expecting (3) files as output:
representative-sequences.qza
table.qza
denoising-stats.qza
Here is the command I am running:
qiime dada2 denoise-paired
–i-demultiplexed-seqs demux-paired-end.qza
–p-trunc-len-f 240
–p-trunc-len-r 240
–o-representative-sequences representative-sequences.qza
–o-table table.qza
–o-denoising-stats denoising-stats.qza
–p-n-threads 8
–verbose &
I have also tried specifying an output directory:
qiime dada2 denoise-paired
–i-demultiplexed-seqs demux-paired-end.qza
–p-trunc-len-f 240
–p-trunc-len-r 240
–output-dir dada2_out
–p-n-threads 8 &
Both attempts generate only one file: table.qza. How do I generate the other (2) files?
Thank you,
Lauren
Hi @ltom ! I suspect the command is not running to completion, sometimes backgrounding a job (adding the &
can make it tricky to tell when it is done. My recommendation is to try again, without backgrounding, and report back. Also, what version of QIIME 2 are you using?

I tried running without backgrounding and I think my run stalled (the resulting output directory is empty). I am trying once more using the following command:
qiime dada2 denoise-paired
–i-demultiplexed-seqs demux-paired-end.qza
–p-trunc-len-f 240
–p-trunc-len-r 240
–output-dir dada2_out_v6
–p-n-threads 8
FYI, I am using the following version of QIIME 2:
