Hi, this is Yunju.
I am working with DADA2 and it takes long time as I anticipated.
However I checked the number of thread of R, it was just ‘1’.
(I thought DADA2 running is mainly composed of R.
So, I wonder can I adjust that to improve the working time of DADA2?
This is the script I used.
+) My data is composed of 491294 sequences(Miseq, Paired-end).
DADA2 is working for 72hrs till now.
