I am trying to run DADA2 using the below command, I have already run the previous step to get the demux-paired-end.qza, unfortunately I am stucked at the DADA2 and can not proceed, the system does not give me any error when I copy-paste the command, the curser blinks for few seconds and then stops... I waited for 10 hours because in my previous analysis (more than a year ago) this step took 9 hours on my mac. I uninstalled/installed Virtual box and qiime2 several times, freed space, etc... but nothing works..Please let me know if there is any solution to proceed. Thank you.
qiime dada2 denoise-paired
I got this error after more than 12 hours, do you have any suggestion? Thank you in advance.
Plugin error from dada2:
An error was encountered while running DADA2 in R (return code -9), please inspect stdout and stderr to learn more.
Debug info has been saved to /tmp/qiime2-q2cli-err-xo8m9xhw.log
can you save that log output and upload it so we can see it? You can use this command:
cat /tmp/qiime2-q2cli-err-xo8m9xhw.log > ~/Desktop/dada2_error_log to save it to your desktop, and subsequently upload it.
You could also try running the command again with the
--verbose flag set. But that might be a secondary step at this point. How big is your data? This is one of those operations that is dependent on the input dataset size, so sometimes it will just take a long time, which is not good if it is erroring out at the end .
Thnx for the reply. I have 66 samples (the initial fastq files folder was 6 GB).
I got this error when I tried to save the log output;
cat: /tmp/qiime2-q2cli-err-xo8m9xhw.log: No such file or directory
and I tried the --verbose and got this error; (1/1) Invalid value for '--i-demultiplexed-seqs': 'paired-end-demux.qza' is
not a valid filepath

@salma_M, can you run
conda list, and
ls in the directory you are trying to run your commands + with your correct conda environment activated? It looks like it is having trouble finding your demultiplexed sequences and is spending a lot of time looking for them. Hopefully by letting QIIME 2 know exactly where they are we can get this working for you
