Given our high-mapping-quality threshold (MAPQ ≥ 30), it is unlikely that many SNV positions in the genome would have high depth because of being in repetitive regions.
The resulting reads had high depth of coverage (> 2000x for each isolate when mapped to the N16961 reference genome using MAQ, a short read alignment tool [ 23]), enabling de novo assembly.
So we need a theory to analyse the beams having higher depth span ratio.
It is clear from the map that the vulnerability is low in the area having higher depth to groundwater and vice versa.
Overall, validated candidate SNPs had higher depth of 454 sequence coverage than non-validated SNPs in both Category 1 and Category 2 SNPs.
Many gorges in the world have higher depth-to-width ratio, but are not as deep, or are much deeper like Peru's Colca Canyon at 10,500 feet and California's Kings Canyon at 8,200 feet, but also much wider.
Since erroneous contigs in high-depth regions may have higher depths than correct contigs in low-depth regions, short (< l) and relatively low-depth contigs are likely to be erroneous and can be removed.
Additional file 1 shows that the genome coverage of the CG, CHG, and CHH sites negatively correlates with read depth; a large number of regions had low-depth coverage, and a small number of regions had high-depth coverage.
Some images in the database were collected from the Middlebury 2005/2006 dataset [38], which has high-accuracy depth maps, while others were produced from videos recorded using a Panasonic AG-3DA1 3D camera, which supplies high-quality left/right images.
Since the left tunnel has higher overburden depth than the right one, in order to reduce tunneling risk such as rock collapse and cave-in, the two tunnels are driven with the conventional drill and blast method.
