I want to filter several samples out from my demux qza file.
I run this: “qiime demux filter-samples --i-demux 1st.bacteria.demux.qza --m-metadata-file 1st-samples-to-filter.tsv --p-exclude-ids --o-filtered-demux 1st.bacteria.demux.filtered.qza”
This is the head of my metafile
I don’t know it is wrong with this script. There is no errors of this script.
I visualize the 1st.bacteria.demux.filtered.qza file, but it still gives same number of samples before and after filtering?
PS, what is exactly the metadata-file format should be like?
