DADA2 Issue with R

Good afternoon,

Thanks for posting your log file! Inside, I found these important lines:

2) Learning Error Rates
Error: cannot allocate vector of size 11.7 Gb
Execution halted
Warning message:
system call failed: Cannot allocate memory 

It looks like you don't have enough RAM / memory to run this command.

My first suggestion would be to run this command with a smaller value for --p-n-reads-learn (it's 1000000 by default). This could let you get through this step.

Let me know if that helps,
Colin
