I use 2015 Macbook Pro, I think my computer is ok, probably because I opened too many tasks.
The problem is that dada2 takes too long, several days passed, it is still running, and I am thinking run dada2 in R and import output back into qiime2. But the tutorial for dada2 in R is for Illumina, do you have any tutorials for ion torrent.
it looks like that only trimLeft =15 is not enough, always give errors in filterAndTrim, let alone the following steps which aim to pair the sequences, after all, Ion Torrent out-put is single end.
Thank you so much.
