I have an OTU table containing my samples and several OTUs.
I would like to conduct an abundance-based filtering where I end up with an OTU table that includes only those OTUs that are present at above a confident level of detection (0.1% relative abundance).
So basically filtering out OTUs <0.1% of total reads.
Could anyone please help me? I’m aware that there is a way of doing this in QIIME1 but I am struggling to find something similar in QIIME2.
