Hey there, I have a problem to get output from this code:

!qiime feature-classifier fit-classifier-naive-bayes
--i-reference-reads bact_seqs_v1v2_clean.qza
--i-reference-taxonomy bact_tax.qza
--o-classifier bact_classifier_v1v2.qza

sequence and taxonomie are cleaned and sequences can be found in taxonomie.fastq data...but this code produce no output data "bact_classifier_....qza"...i get no error message....everything looks fine, but its not working.
I use wsl ubuntu environment and qiime2-amplicon-2024.10

Thanks for any ideas!

Hello and welcome to the forum!

I had similar issues several times - there was no error, and no output files and the reason was insufficient RAM.

You would try one of the options:

  • Decrease "--p-classify--chunk-size" (default 20000)
  • Search for the machine with higher RAM available (computer room...)

Best,
Timur
