I am aware that many people are confused about the definition of structural zeros, so the following clarifications have been added to the new ANCOMBC release A taxon is considered to have structural zeros in some (>=1) groups if it is completely (or nearly completely) missing in these groups. Our second analysis method is DESeq2. # tax_level = "Family", phyloseq = pseq. Step 1: obtain estimated sample-specific sampling fractions (in log scale).
