| MAG coverage depth | 10.38 |
|---|
| MAG coverage software | Reads (ERR7745815) were merged using BBMerge (rem k=62 extend2=50 ecct vstrict) and then mapped to assembled contigs >=1500bp (ERZ4567746) 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 ERR7745815 were assembled into contigs (ERZ4567746). The following read sets from this study were the most similar to ERR7745815 as determined by MASH (-r -m 2 -s 100000 -k 32): ERR7745815,ERR7738569,ERR7746365,ERR7746184,ERR7738200,ERR7746321,ERR7738610,ERR7738461,ERR7738559,ERR7738606. 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 ERZ4567746. 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. |
