WebMate pair sequencing involves generating long-insert paired-end DNA libraries useful for a number of sequencing applications, including: Combining data generated from mate pair library sequencing with that … WebWe further refer to paired-end and mate-pair libraries simply as to read-pair libraries. By default, SPAdes assumes that paired-end and high-quality mate-pair reads have forward-reverse (fr) orientation and usual mate-pairs have reverse-forward (rf) orientation. However, different orientations can be set for any library by using SPAdes options.

WebMar 28, 2011 · The paired de bruijn graph is introduced, a generalization of the de Bruijn graph that incorporates mate pair information into the graph structure itself instead of analyzing mate pairs at a post-processing step to effectively improve the contig sizes in assembly. The recent proliferation of next generation sequencing with short reads has … WebJun 15, 2015 · Motivation: Mate pair protocols add to the utility of paired-end sequencing by boosting the genomic distance spanned by each pair of reads, potentially allowing larger repeats to be bridged and resolved.
