Error in DADA2 denoise-ccs (return code -6)

Hello, I'm Hanbeen Kim.

I'm trying to analyze CCS data from Pacbio using QIIME2.

I got the error when running dada2 denoise-ccs.

The error code was:

An error was encountered while running DADA2 in R (return code -6), please inspect stdout and stderr to learn more.

The command I used was:

qiime dada2 denoise-ccs
--i-demultiplexed-seqs 220829_Input.qza
--p-min-len 1000
--p-max-len 1650
--o-table bac_table.qza
--o-representative-sequences bac_seq.qza
--o-denoising-stats bac_stats.qza
--p-n-threads 0

The debug for this error is here.

Version of QIIME2:

Can you give me some recommendations?

Hi @khb3850,

Welcome to the :qiime2: forum!

This looks like an error you would get if your system’s scheduling software terminated your job. I’m not exactly sure what’s going on here, but this often happens when your commands exceed some resource allocation (time, memory, etc.).

If you need a quick fix, your best bet might be to try running on a different system. Unless your samples are very large, this could be a strong laptop or a desktop computer. If your machine was provided by your employer or university, it might be worth talking to your sysadmin about these issues. This will let you confirm that your job allocations are reasonable, and might get you some insight into how to interpret or correct the errors you’re running into.

Hope this helps!
Cheers :lizard:
