Small amounts of misassembly can have disproportionate effects on pangenome-based metagenomic analyses
journals.asm.org
Metagenome-assembled genomes, or MAGs, can be constructed without pure cultures of microbes. Large-scale efforts to build MAGs have yielded more complete pangenomes (i.e., sets of all genes found in...
