the weighted median item size or N50 is a weighted median of the lengths of items, equal to the length of the longest item i such that the sum of the lengths of items greater than or equal in length to i is greater than or equal to half the length of all of the items. With regard to assemblies the items are typically contigs or scaffolds. It therefore denotes the ability of the software to create contigs and provides information about the resulting sequence assembly
