WebNov 8, 2024 · The dada2 package is centered around the DADA2 algorithm for accurate high-resolution of sample composition from amplicon sequencing data. The DADA2 algorithm is both more sensitive and more specific than commonly used OTU methods, and resolves amplicon sequence variants (ASVs) that differ by as little as one nucleotide. WebJul 28, 2024 · The problem is that getUniques expects a single sample, and you have given it all the samples at once ( dadaFs is a list of dada-class obejcts, one for each sample).
