Explore metagenomics analysis and taxonomic classification using Kraken 2 in BioBam's OmicsBox tool in this 42-minute video tutorial. Learn about targeted sequencing and shotgun WGS approaches, metagenomics workflows, and research applications. Follow a case study demonstrating study design and practical analysis steps. Witness quality control, pre-processing, taxonomic classification, and output interpretation on the OmicsBox platform. Gain insights into FastQC reports, read trimming with Trimmomatic, Kraken 2 classification, and visualization techniques like Krona charts, principle coordinate analysis, and stacked bar charts. Conclude with an overview of differential abundance analysis for taxa.
