In July '22 @jwdebelius provided excellent information re: principal component and redundancy analysis in QIIME2. In it, she explains why Aitchison distance is not suggested for use since it does not account for zeros in gut microbiome data, preferring instead to use DEICODE as a means of tackling the compositional nature and sparsity of gut microbiome data.
I wonder if the use of coda4microbiome (Malue Calle and Toni Susin) appropriately resolves the concerns raised in that post regarding use of Aitchison?
