  • NADfinder is the first software designed specifically for the bioinformatic analysis of the NAD-seq data, including baseline correction, smoothing, normalization, peak calling, and annotation. (umassmed.edu)
  • This package is for the visualization of multi-omics data that can be integrated into any analysis pipeline in R. trackViewer can be used not only to visualize coverage and annotation tracks, but also to generate lollipop and dandelion plots that depict sparse and dense methylation/mutation/variant data to facilitate an integrative analysis of diverse datasets. (umassmed.edu)
  • Therefore, these data will help toward better understanding of genome functioning and designing effective anti-viral therapeutics. (researchgate.net)
  • T-lex is a computational pipeline that detects presence and/or absence of annotated individual transposable elements (TEs) using next-generation sequencing (NGS) data. (stanford.edu)
  • T-lex starts by extracting the TE junction sequences and the NGS data are converted into binary formats (bfa and bfq, respectively). (stanford.edu)
  • Xie, Boyle and Snyder designed a machine-learning algorithm to analyze all the data and identify which trans-acting factors tend to be seen together and which DNA sequences they prefer. (pharmaceuticalintelligence.com)
  • used genotyping-by-sequencing to build a genome linkage map of P. angustifolia [4]. (peercommunityin.org)
  • The level of conservation of gene order (synteny) and linkage between two genomes will depend on the relative contributions of inter- and intrachromosomal rearrangements. (biomedcentral.com)
  • We envision that re-routing of sources could occur by altering the dimensions of the sink, by reconfiguration of existing sink occupation or by varying the size of the source, providing a central mechanism to explain a plethora of epigenetic phenomena, which contribute to phenotypic variegation, zygotic genome activation and nucleolar dominance.

  • Genome instability and aberrant alterations of transcriptional programs both play important roles in cancer. (pklab.org)
  • Class I TEs, also called retrotransposons, first transcribe an RNA copy that is then reverse transcribed to cDNA before inserting in the genome. (bioconductor.org)
  • Paired-end sequencing was performed by the Illumina HiSeq 2000 system. (biomedcentral.com)
  • Annotation largely depends on identifying relationships between sequences through the use of sequence alignment. (umt.edu)
  • Modern methods for sequence alignment are remarkably good at recognizing when a substring of one sequence is related (aligns) to a substring of another sequence, but are also prone to a form of error known as alignment overextension, in which the alignment extends beyond the true bounds of relatedness. (umt.edu)
  • We present a 152-Mb draft assembly of the M. occidentalis genome: Larger than that of its favored prey, Tetranychus urticae, but considerably smaller than those of many other chelicerates, enabling an extremely contiguous and complete assembly to be built-the best arachnid to date. (bcm.edu)
  • After acute injury in muscle of both mouse and the fruit fly Drosophila melanogaster (used as alternative in vivo model) this study found that RACK1 accumulated in regenerating fibers while it declined with the progression of repair process. (sdbonline.org)
