Abstract
The present invention relates to gene engineering filed, and provides a genome sequencing device, construction method of fragments assembling scaffold and system thereof. The method comprises the following steps: mapping the double-barreled data obtained through sequencing to contigs; calculating the mean length between contigs based on multiple pairs of double-barreled data mapped to contigs, which is taken as the gap size between contigs; constructing scaffold based on gap size between contigs and the double-barreled relation between contigs; and obtaining complete scaffold graph. Since the mean length between contigs is calculated from multiple pairs of double-barreled data and is taken as the gap size between contigs, the estimation precision of gap size between contigs is improved greatly. It can be used for genome sequencing including short sequencing read length to finish task of assembling sequencing fragments.
