LoRMA: A tool for correcting sequencing errors in long reads
By Abhimanyu Singh 2317 days agogite.lirmm.fr - An error correction method that uses long reads only. The method consists of two phases: first, we use an iterative alignment-free correction method based on de Bruijn graphs with increasing length of k-mers, and second, the corrected reads are...Rainbow: an integrated tool for efficient clustering and assembling RAD-seq reads
By Rahul Nayak 2275 days agosourceforge.net - Rainbow is developed to provide an ultra-fast and memory-efficient solution to clustering and assembling short reads produced by RAD-seq. First, Rainbow clusters reads using a spaced seed method. Then, Rainbow implements a heterozygote calling like...Genome assembly tutorial "Genome Assembly for short and long reads"
By Jit 2182 days ago Comments (1)bioinformaticsdotca.github.io - In this lab we will perform de novo genome assembly of a bacterial genome. You will be guided through the genome assembly starting with data quality control, through to building contigs and analysis of the results. At the end of the lab you will...SViper: Swipe your Structural Variants called on long (ONT/PacBio) reads with short exact...
By Neel 1846 days agogithub.com - Call sviper ~$ ./sviper -s short-reads.bam -l long-reads.bam -r ref.fa -c variants.vcf -o polished_variants This will output a polished_variants.vcf file, that contains all the refined variants. Sometimes it is helpful to look at the...Rcorrector: efficient and accurate error correction for Illumina RNA-seq reads
By BioStar 1801 days agogithub.com - Rcorrector has an accuracy higher than or comparable to existing methods, including the only other method (SEECER) designed for RNA-seq reads, and is more time and memory efficient. With a 5 GB memory footprint for 100 million reads, it can be run...SLR-superscaffolder: A scaffold assemble pipeline for stLFR reads.
By Jit 1791 days agogithub.com - This is a scaffold assembler designed for stLFR reads[1]. It uses the link-reads information from stLFR reads to assemble contigs to scaffolds. Here is an illustration of this pipeline:KAD: Assessing genome assemblies using K-mer copies in assemblies and K-mer abundance in Illumina...
By Jit 1666 days agogithub.com - KAD is designed for evaluating the accuracy of nucleotide base quality of genome assemblies. Briefly, abundance of k-mers are quantified for both sequencing reads and assembly sequences. Comparison of the two values results in a single value per...FastProNGS: fast preprocessing of next-generation sequencing reads
By Rahul Nayak 1476 days agogithub.com - FastProNGS to integrate the quality control process with automatic adapter removal. Parallel processing was implemented to speed up the process by allocating multiple threads. Compared with similar up-to-date preprocessing tools, FastProNGS is by...
Short-read assembly using Spades !
Last updated 1075 days ago by Abhimanyu Singh Comments (2)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...SqueezeMeta: a fully automated metagenomics pipeline, from reads to bins
By BioStar 188 days agogithub.com - SqueezeMeta is a full automatic pipeline for metagenomics/metatranscriptomics, covering all steps of the analysis. SqueezeMeta includes multi-metagenome support allowing the co-assembly of related metagenomes and the retrieval of individual genomes...
