I want to know how hgap select the seed. The paper says it selects the seed with more than 20x coverage, but doesn't say how it counts the coverage.

The seed will be selected automatically if you input the expected genome size. Coverage is a simply number of bases / genome size. -
Do that mean the automatically selected seeds are long enough and has enough coverage? Does it calculate kmer frequency?Comment

HGAP is an overlap consensus based assembler and thus no kmer statistics are computed during the assembly process.Originally posted by Rui Guo View Post
As rhall stated, When you set up the run, you input a Genome Size (bp). The algorithm will sort the subreads by length, compute the quantity of bases necessary to obtain appropriate coverage for the Genome Size (bp) that you input during setup and select the longest data necessary to obtain the 30X coverage.

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Today, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
