(A) Per-site coverage of trusted and untrusted assembly based on mappings of Moleculo reads. Contigs from the untrusted assembly generally don’t share the coverage of the trusted, most likely nuclear, genome. (B) GC content of trusted and untrusted assembly estimated using sliding window approach. The untrusted assembly contains multiple peaks pointing toward contig subpopulations with different GC content. (C) Per-site variability of trusted and untrusted assembly, which can serve as ploidy proxy. The untrusted variability spectrum seems distorted and contains a multitude of different peaks, whereas the trusted assembly shows a typical diploid spectrum. (D) Length distribution of intergenetic regions. Intragenetic regions are significantly larger in the trusted assembly than in the untrusted.

Circular map of an unknown bacterial genome probably belonging to the Chitinophagaceae drawn with CGView. Tracks 1 and 2 (blue) indicate GeneMark-S annotated genes on forward and reverse strand. Track 3 (red) visualizes regions of homology to a set of 30,844 Chitinophagaceae proteins downloaded from UniProtKB. Track 4 (green) shows homology between GeneMark-S predicted proteins and the published protein set of ref. .
