Using Sandpiper - the result of SingleM applied to public metagenomic datasets, available at https://sandpiper.qut.edu.au - we devised a simple procedure to suggest datasets likely to yield novel genomes based upon the estimated coverage and relative abundance of the taxa of interest. To test the procedure, we attempted recovery of metagenome assembled genomes (MAGs) from four related bacterial phyla, the Muirbacteria, Wallbacteria, Riflebacteria and Fusobacteria.
