Hi, I have been trying to train the classifier in the V3-V4 region (16S_341F CCTACGGGNGGCWGCAG 16S_806R GACTACHVGGGTATCTATCC) using the following command:
qiime feature-classifier fit-classifier-naive-bayes --i-reference-reads ref_seqs_16S_V3-V4.qza --i-reference-taxonomy 99_otus_16S_taxonomy.qza --o-classifier classifier_16S_V3-V4.qza --verbose
However, it always ends with a memory error and the process is killed. I have read through the internet that a possible alternative is to set --p-reads-per-batch argument to a lower value than the one by default, but I think this argument is no longer available. Do you know how could I solve this issue?
My version of qiime is qiime2-2022.11. Thank you in advance for your time and assistance,
