QuorUM: An Error Corrector for Illumina Reads
By Jit 3192 days agojournals.plos.org - Illumina Sequencing data can provide high coverage of a genome by relatively short (most often 100 bp to 150 bp) reads at a low cost. Even with low (advertised 1%) error rate, 100 × coverage Illumina data on average has an error in some read...QuorUM: An Error Corrector for Illumina Reads
By BioStar 2373 days agowww.genome.umd.edu - We produce trimmed and error-corrected reads that result in assemblies with longer contigs and fewer errors. We compared QuorUM against several published error correctors and found that it is the best performer in most metrics we use. QuorUM is...The "Ifs" and "Buts" of NGS Quality Control and Trimming
By BioStar 579 days agoNGS quality control and trimming are essential steps to ensure reliable and accurate data for analysis. While the "ifs" highlight the clear benefits of these steps, the "buts" remind us of the potential pitfalls. By adopting best practices and...Comparison of Short Read De Novo Alignment Algorithms
By Rahul Agarwal 4732 days agobiochem218.stanford.edu - Excellent article to introduce different sequencing methods along with tools for de novo assembly of sequencing reads and their relevant references. Title: Comparison of Short Read De Novo Alignment Algorithms Author: Nikhil GopalPERGA: A Paired-End Read Guided De Novo Assembler for Extending Contigs Using SVM and Look Ahead...
By Rahul Nayak 2983 days agogithub.com - PERGA - Paired End Reads Guided Assembler PERGA is a novel sequence reads guided de novo assembly approach which adopts greedy-like prediction strategy for assembling reads to contigs and scaffolds. Instead of using single-end reads to construct...ASplice: a scalable and memory-efficient algorithm for de novo transcriptome assembly
By Rahul Nayak 2955 days agofaculty.cse.tamu.edu - With increased availability of de novo assembly algorithms, it is feasible to study entire transcriptomes of non-model organisms. While algorithms are available that are specifically designed for performing transcriptome assembly from...MEGAHIT: an ultra-fast single-node solution for large and complex metagenomics assembly via...
By Jit 2821 days agogithub.com - MEGAHIT is a single node assembler for large and complex metagenomics NGS reads, such as soil. It makes use of succinct de Bruijn graph (SdBG) to achieve low memory assembly. MEGAHIT can optionally utilize a CUDA-enabled GPU to...SDA: Long-read sequence and assembly of segmental duplications
By Jit 2710 days agowww.nature.com - Segmental Duplication Assembler (SDA; https://github.com/mvollger/SDA) constructs graphs in which paralogous sequence variants define the nodes and long-read sequences provide attraction and repulsion edges, enabling the partition and assembly of...Merfin: improved variant filtering, assembly evaluation and polishing via k-mer validation
By Neel 1584 days agogithub.com - 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...Picard
By Neel 3750 days agobroadinstitute.github.io - Picard is a set of command line tools for manipulating high-throughput sequencing (HTS) data and formats such as SAM/BAM/CRAM and VCF. These file formats are defined in the Hts-specs repository. See especially the SAM specification and the VCF...
