Scaffolds contigs

WebIn computational biology, N50 and L50 are statistics of a set of contig or scaffold lengths. The N50 is similar to a mean or median of lengths, but has greater weight given to the longer contigs. It is used widely in genome assembly, especially in reference to contig lengths within a draft assembly. There are also the related U50, UL50, UG50 ... WebWhat is a scaffold N50? Scaffold N50 – length such that scaffolds of this length or longer include half the bases of the assembly. Scaffold L50 – number of scaffolds that are longer than, or equal to, the N50 length and therefore include half the bases of the assembly. Number of Contigs – total number of sequence contigs in the assembly.
