Hi everyone,
I am running QIIME2 2019.4 in a Virtual Box, and I ran the following command:
qiime dada2 denoise-paired
–p-n-threads 3
–i-demultiplexed-seqs name of samples .qza
–p-trim-left-f 17
–p-trim-left-r 21
–p-trunc-len-f 278
–p-trunc-len-r 219
–o-table table_ name of samples .qza
–o-representative-sequences rep-seqs_ name of samples .qza
–o-denoising-stats denoising- name of samples .qza
And received this error:
An error was encountered while running DADA2 in R (return code -9) please inspect stdout and stderr to learn more.
The error log file says:
Running external command line application(s). This may print messages to stdout and/or stderr.
The command(s) being run are below. These commands cannot be manually re-run as they will depend on temporary files that no longer exist.

I looked at several similar topics, but I didn’t find anything exactly like mine. I don’t know how to interpret this error. Any idea?
I will appreciate any help. I’ve been trying to solve this for 3 days 
Thanks!
