DADA 2 error (return code -15)

Hello All:

I am running running my data through DADA 2 and have gotten a error that I have never gotten before.

An error was encountered while running DADA2 in R (return code -15), please inspect stdout and stderr to learn more.

Everything was going well prior to this and I am at a loss as to what it could be.

This is the entirety of the code:

(qiime2-2021.2) bash-5.0$ qiime dada2 denoise-paired \

–i-demultiplexed-seqs NSAID-demux.qza
–p-trim-left-f 10
–p-trim-left-r 10
–p-trunc-len-f 0
–p-trunc-len-r 0
–o-table NSAIDFeatureTable[Frequency]
–o-representative-sequences NSAIDFeatureData[Sequence]
–o-denoising-stats NSAIDSampleData[DADA2Stats}

Any help or insight would be greatly appreciated.

Hi there @gpgarcia!

Are you running this on an HPC or institutional computer? I ask because this is the main part of the error:

That means the operating system terminated your command - usually we see this happen when an HPC queueing system terminates a job - usually because you didn't ask for enough time when you launched. If this is on an institutional server, please check with your sysadmin to see what you need to do to request adequate time and other resources.



Thank you so much for your reply! I will get in touch with the sysadmin and hopefully that will fix it!
