I'm trying to run a taxonomic classification with feature-classifier classify-sklearn, thank to the silva database, and I encounter long runtime issues.
For example, I'm currently testing on a subset of 8 first sequences coming from the "moving picture" tutorial (from file rep-seqs.qza), and it has been running for more than 3 hours without success. I have 8 cpus and 32Gb of RAM available and all ressources are used non-stop without any errors.
here is the command I used :
qiime feature-classifier classify-sklearn \ --i-classifier /home/qiime2/tutorial/silva-138-99-515-806-nb-classifier_qiime.qza \ --i-reads /home/qiime2/tutorial/sequence_table_subset_8ASV.qza \ --o-classification /home/qiime2/tutorial/taxonomy_silva.qza \ --p-n-jobs -1
I understand from this benchmark that it should take that long : https://github.com/qiime2/q2-feature-classifier/issues/97
I'm not sure where to look for to know what the problem could be, any advice would be very helpful !
Thank you in advance for your help,
