Hi everybody :),
i have a problem.
While running an analysis i calculated the core features of my samples using the command : "qiime feature-table core-features" on the rarefied table.qza. The resulting .qzv suggested i had no core features until i consider 70% of the samples (under column: fraction of samples).
While looking at the rarefied relative feature table and confronting it with these core features i noticed that some of the features actually where in all the samples (100%!!!)... why is this appening? are there other ways to calculate core features?
Thank you very much,
Michele
