Alignment-free RNA quantification tools have significantly increased the speed of RNA-seq analysis. However, it is unclear whether these state-of-the-art RNA-seq analysis pipelines can quantify...

High-throughput sequencing has transformed the study of gene expression levels through RNA-seq, a technique that is now routinely used by various fields, such as genetic research or diagnostics. The advent of third generation sequencing technologies providing significantly longer reads opens ...

Alignment is the first step in most RNA-seq analysis pipelines, and the accuracy of downstream analyses depends heavily on it. Unlike most steps in the pipeline, alignment is particularly amenable to benchmarking with simulated data. Researchers from the University of ...

Quality control (QC) is a critical step in RNA sequencing (RNA-seq). Yet, it is often ignored or conducted on a limited basis. Here, Vanderbilt University researchers present a multi-perspective strategy for QC of RNA-seq experiments. The QC of RNA-seq can ...

Driver somatic mutations are a hallmark of a tumor that can be used for diagnosis and targeted therapy. Mutations are primarily detected from tumor DNA. As dynamic molecules of gene activities, transcriptome profiling by RNA sequence (RNA-seq) is becoming increasingly ...

from RoBlog by Rob Patro – Thoughts and musings on science and life Introducing RapMap I’ve recently been working with my student Avi Srivastava on a new project, RapMap.  RapMap is a tool for mapping (see below for the distinction between mapping ...

Canadian Bioinformatics Workshops – Informatics for RNA-sequence Analysis (QC) (2014) – Module 2 – RNA-seq alignment and visualization High-throughput sequencing of RNA libraries (RNA-seq) has become increasingly common and largely supplanted gene microarrays for transcriptome profiling. When processed appropriately, RNA-seq ...

The fundamental task in RNA-Seq-based transcriptome analysis is alignment of millions of short reads to the reference genome or transcriptome. Choosing the right tool for the dataset in hand from many existent RNA-Seq alignment packages remains a critical challenge for ...

RNA-Seq experiments have revealed a multitude of novel ncRNAs. The gold standard for their analysis based on simultaneous alignment and folding (Sankoff, 1985) suffers from extreme time complexity of O(n6). Subsequently, numerous faster “Sankoff-style” approaches have been suggested. Commonly, the ...

Important changes in this major release include: Advanced and comfortable search in a project Usability: Sequence Viewer resizing Regrouping of the Tools menu items Workflow Designer: generating of output file names Sanger reads quality control and alignment NGS: Reads quality ...
