| MAG coverage depth | 153.57 |

| MAG coverage software | Reads (ERR7745408) were merged using BBMerge (rem k=62 extend2=50 ecct vstrict) and then mapped to assembled contigs >=1500bp (ERZ4561111) using Bowtie2 v2.3.4 (--very-sensitive -X 1000). Coverage was calculated using jgi_summarize_bam_contig_depths (default parameters) from MetaBAT2 v2.15. |

| binning parameters | Reads from ERR7745408 were assembled into contigs (ERZ4561111). The following read sets from this study were the most similar to ERR7745408 as determined by MASH (-r -m 2 -s 100000 -k 32): ERR7745408,ERR7745881,ERR7745743,ERR7738168,ERR7745563,ERR7738266,ERR7745914,ERR7745759,ERR7746411,ERR7738264. Following processing using BBMerge (rem k=62 extend2=50 ecct vstrict), reads from each of these 10 samples were mapped using bowtie2 v2.3.4 (--very-sensitive -X 1000) onto contigs >=1500bp from ERZ4561111. Depth information for all 10 mapped samples was utilized by MetaBAT2 2.15 for genome binning. Contigs flagged by any module in MAGpurify 2.1.0 (--weighted mode for gc_content, tetra_freq, and coverage modules; conspecific database augmented by high-quality MAGs from this study) were removed from the bin. |
