Fig. 2

The map of coverage distribution, neighboring coverage ratio (NCR) and read edge frequencies of phage isolate I13. a An illustration of hypothetical genome configuration of I13 with terminal repeats. Filled squares indicate the direct terminal repeat of phage genome. b Coverage distribution over I13 sequence contig. The lower dashed line represents the average coverage of I13 sequencing reads. The upper dashed line represents the level of 1.8 times of average coverage. c Neighboring coverage ratio (NCR) over I13 sequence contig with window size = 100 bp. The dashed lines indicate the cut-off of 1.8 and reciprocal of 1.8 of NCR after base-2 logarithmic transformation [−0.848, 0.848]. d 5′ or 3′ read edge frequencies from I13 sequencing reads. Filled black squares indicate the frequencies of 5′ read edge positions. Blank triangles indicate the frequencies of 3′ read edge position
