Short-read assembly using Spades !
If we only had Illumina reads, we could also assemble these using the tool Spades. You can try this here, or try it later on your own data. Get data We will use the same Illumina data as we used above: illumina_R1.fastq.gz: the Illumina forward reads illumina_R2.fastq.gz: the Illumina reve...Tags: spades, assembly, short, reads, genome, tools

Merfin: improved variant filtering, assembly evaluation and polishing via k-mer validation
Merfin, a k-mer based variant-filtering algorithm for improved accuracy in genotyping and genome assembly polishing. Merfin evaluates each variant based on the expected k-mer multiplicity in the reads, independently of the quality of the read alignment and variant caller’s interna...Tags: Merfin, improved, variant, filtering, assembly, evaluation, polishing, k-mer, validation

auN: a new metric to measure assembly contiguity
Given a de novo assembly, we often measure the “average” contig length by N50. N50 is neither the real average nor median. It is the length of the contig such that this and longer contigs cover at least 50% of the assembly. A longer N50 indicates better contiguity. We can si...Tags: auN, new, metric, measure, assembly, contiguity

Mitochondrial genome assembly tools !
Mitochondrial genome assembly tools are specialized software and algorithms designed to accurately reconstruct the mitochondrial genome (mitogenome) from sequencing data, typically obtained through techniques like next-generation sequencing (NGS). The mitochondrial genome is relatively small comp...Tags: Mitochondrial, genome, assembly, tools

MIKE: an ultrafast, assembly-, and alignment-free approach for phylogenetic tree construction
MIKE (MinHash-based k-mer algorithm). This algorithm is designed for the swift calculation of the Jaccard coefficient directly from raw sequencing reads and enables the construction of phylogenetic trees based on the resultant Jaccard coefficient. Simulation results highlight the superior sp...Tags: MIKE, ultrafast, assembly, alignment-free, approach, phylogenetic, tree, construction
