Fig 5. Procrustes analysis of the 16S rRNA gene metabarcoding-based datasets with the functional community of the metagenomics data. The amplicon sequence variant (ASVs) and Paprica datasets were fitted with the Enzyme commission numbers (EC) profiles while Picrust2 and Tax4Fun2 were fitted with the KEGG ortholog numbers (KO) profiles of the metagenomics data.
