I know variations of this question have been posted but there are a few things I would like to clarify…
I have come to the end of my QIIME2 pipeline and the taxa bar plots are showing the blanks/negatives that are in my metadata sheet.
Is there a way to remove the blanks/negatives from my metadata sheet or taxa bar plot?
I know there are the filtering steps (metadata based filtering), however I don’t quite understand how they work: it seems you list the samples you would like to keep rather than remove (because there are way more samples I would like to keep rather than remove, so it would be logical to state what I would like to remove instead?).
Or do I need to go way back to the beginning of the pipeline, and create a metadata sheet without those samples, and re-do analysis without the negatives in it?
Thanks for any help
