This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Metagenomics is a powerful technique for studying complex microbial communities. The key computational step in this method is clustering genomic sequences from mixed samples into potential microbial genomes, but accurately classifying sequences from complex metagenomes remains challenging. Some tools depend on k-mer frequency and coverage, but such methods struggle to distinguish between similar genomes. Methods that address the similar genomes problem, like ones that rely on single-copy marker genes, in turn struggle with complex datasets. The newly developed MetaDecoder balances these challenges by using both types of methods broken into two steps. First, MetaDecoder simplifies the dataset by generating preliminary groups of sequences with the Dirichlet Process Gaussian Mixture Model (DPGMM). Then, these preliminary clusters are clustered further with a k-mer frequency probabilistic model and a modified Gaussian Mixture Model of single-copy marker gene coverage..."
