#GENOME SCAFFOLD MEANING FULL#

Despite the progress made in de novo assembly algorithms, quality of short read assemblies is far from what is necessary for effective further analysis due to the fundamental limit - the read length is shorter than repeat lengths for the majority of repeat classes. The advent of massively parallel sequencing technologies has made the generation of billions of reads possible at a very low-cost per sequenced base. Our new algorithm SALSA produces more accurate scaffolds compared to the existing state of the art method LACHESIS. We compare our scaffolds with the scaffolds generated by LACHESIS based on various metrics. We tested our methods on the human and goat genome assemblies. We demonstrate an algorithm that uses Hi-C data for longer-range scaffolding of de novo long read genome assemblies. We develop a scalable and computationally efficient scaffolding method that can boost the assembly contiguity to a large extent using genome-wide chromatin interaction data such as Hi-C. To increase the contiguity of the assembly to the chromosome level, different strategies are used which exploit long range contact information between chromosomes in the genome.

#GENOME SCAFFOLD MEANING FULL#

Although assembly contiguity has increased, it usually does not reconstruct a full chromosome or an arm of the chromosome, resulting in an unfinished chromosome level assembly. Long read technologies have revolutionized de novo genome assembly by generating contigs orders of magnitude longer than that of short read assemblies.
