Hello! I am currently working on the DADA2 step in the qiime2 workflow. My data was already demultiplexed prior to qiime2 analysis (data was retrieved from SRA repository, so the details i have about the data is info provided on SRA as well as the paper). i successfully loaded the data as an artifact and was able to summarize it to look at the average quality over the reads to instruct my dada2 parameters. I then input the data with the following parameters into DADA2
qiime dada2 denoise-paired --i-demultiplexed-seqs pe-demux.qza --p-trunc-len-f 20 --p-trunc-len-r 20 --o-table table.qza --o-representative-sequences rep-seqs.qza --o-denoising-stats denoising-stats.qza --verbose
I have tried to run it a few times and am consistently getting this error:
Input must be a valid sequence table.
Calls: removeBimeraDenovo -> isBimeraDenovoTable

I found a forum question that pointed to the number of threads being used as a possible explanation, but i have reduced the threads from 24 to 6, and am still getting the same error.
I am running qiime2 on an HPC with Qiime natively installed (not in my own personal conda environment).
Thanks for helping!
