Metabarcoding data processing using dada2 - 16S

Using the code in this file, we will process 16S metabarcoding data using the Dada2 pipeline. (DATA REDUCTION STAGE). Our goal is to use the DADA2 algorithm to assess read quality, denoise, and merge our sequences. Finally, we will assign our sequences to ASVs and assign these to taxonomy using DADA2 and a reference database.
