Hi, I think that you are running out of memory, how strong is your machine? If not very strong, you can try perform quality filtering first to get read of excessive reads
Hi!!
It has 8 Mb of RAM, but I’m not sure how much takes Virtual Box to run Qiime2. I think this details cann’t be change once Qiime2 package has been loaded on VB.
Do you know how much memory is necessary to use Qiime2?
8 gb, I suppose, not 8 mb =). I don’t know exactly but once I took a look in htop during DADA2 and it was taking about 7 gb of RAM. You can filter your data to decrease the ammount of processes or try use half of the number of your threads using
–p-n-threads
You should be able to change the allocation - please check out virtualbox.org for links to their docs/support forum/etc (we do not develop Virtualbox).
There is no single answer to this, since every dataset and analysis of it is totally unique. As far as DADA2 goes, please see the following:
