So as a test I used just a single sample and I concatenated the fw and rv reads. That ran through the import fine. I did get an usual comment on the interactive quality plot (see file attached). The comment was in red and said “The plot at position 157 was generated using a random sampling of 5071 out of 1475320 sequences without replacement. This position (157) is greater than the minimum sequence length observed during subsampling (58 bases). As a result, the plot at this position is not based on data from all of the sequences, so it should be interpreted with caution when compared to plots for other positions. Outlier quality scores are not shown in box plots for clarity.” Any help on the dummy version of what this is saying?
Secondly, when I tried to use dada2 denoise on this sequence just as a test I got an error that I don’t quite understand either. It is the following and its long so I apologize for that:

Are these two errors somehow related? If they are any idea what might be causing them? This is just from a single sample, single fw and single rv fastq. I did concatenate them by hand, but that shouldn’t be a huge issue I don’t think. I was pretty careful when I did it.
Any advice on how to get this fixed?
