How to delete negative controls from the files ?


I performed taxa classification via HITDB, at the final step using the following command and when i visualized the qzv file, i realized that i didn't remove 3 negative controls samples from the files table.qza and from rep-seqs.qza. How can i delete those samples to get only a barplot file with required samples?

qiime taxa barplot
–i-table table.qza
–i-taxonomy HITdb_taxonomy_qiime2.qza
–m-metadata-file sample-metadata.tsv
–o-visualization HITdb_taxa-bar-plots2.qzv


You can delete your negative controls from metadata file or create a new metadata file without negative controls and filter feature table using this command
Good luck!
