De Novo Genome Assembly

Description

De novo sequencing refers to sequencing a novel genome where there is no reference sequence available for alignment. Sequence reads are assembled as contigs, and the coverage quality of de novo sequence data depends on the size and continuity of the contigs (ie, the number of gaps in the data).

Parameters

$n$: sum of lengths of reads

$f$: number of input sequences
