String graph based genome assembly software and tools !
In graph theory, a string graph is an intersection graph of curves in the plane; each curve is called a "string". String graphs were first proposed by E. W. Myers in a 2005 publication. In recent Genome Research paper describing an...Tags: String, graph, genome, assembly, software, tools !

Converting a VCF into a FASTA given some reference !
Samtools/BCFtools (Heng Li) provides a Perl script vcfutils.pl which does this, the function vcf2fq (lines 469-528) This script has been modified by others to convert InDels as well, e.g. this by David Eccles ./vcf2fq.pl -f <input.fasta> <all-site.vcf> ...Tags: Convert, VCF, FASTA, reference, genome, assembly, phase

CANU genome assembly parameters !
Choose the appropriate parameters to run Canu and run it. The assembly will take about an hour. You can use two cores (parameter -maxThreads=2) and you would like to disable cluster option, since we compute on a single Amazon server set off the option to compute on cluster useGrid=false...Tags: CANU, genome, assembly, parameters, NGS, LongReads, OLC

Protocol for De novo Genome Assembly using Illumina Reads
In this protocol, we address and describe the de novo assembly method for small to medium-sized genomes. What is de novo genome assembly?The method of taking a large number of short DNA sequences and placing them back together to create a reflection of the original chromosomes from which the DNA...Tags: Protocol, De novo, Genome, Assembly, Illumina, Reads
