RNA-Seq    is a technique  that allows transcriptome studies see also Transcriptomics technologies based on next-generation sequencing technologies.
Since the invention of next-generation RNA sequencing RNA-seq technologies, they have become a powerful tool to study the presence and quantity of RNA molecules in biological samples and have revolutionized transcriptomic studies on bulk tissues. Recently, the emerging single-cell RNA sequencing scRNA-seq technologies enable the investigation of transcriptomic landscapes at a single-cell resolution, providing a chance to characterize stochastic heterogeneity within a cell population. The analysis of bulk and single-cell RNA-seq data at four different levels samples, genes, transcripts, and exons involves multiple statistical and computational questions, some of which remain challenging up to date. The first part of this dissertation focuses on the statistical challenges in the transcript-level analysis of bulk RNA-seq data. The next-generation RNA-seq technologies have been widely used to assess full-length RNA isoform structure and abundance in a high-throughput manner, enabling us to better understand the alternative splicing process and transcriptional regulation mechanism.
As part of its work with the Babraham Institute, the Bioinformatics group runs a regular series of training courses on many aspects of bioinformatics. These courses are run regularly on the Babraham site but we are also able to come out and present them on other sites and also deliver them remotely. You can see the list of current Babraham dates which are available, and you can contact us to discuss options for running courses on your site. You can also sign up to our mailing list to get the latest training news delivered direct to your inbox every couple of months. Where possible we also aim to make the material from our courses publicly available so that anyone who wants to can download them for their own use. Below is a list of the courses we currently run.
Tools for assembly graph analysis via SPAdes toolbox and more talk , You will learn the basics of. This section describes three of the many approaches: hierarchical agglomerative, partitioning, and model It requires the analyst to specify the number of clusters to extract. To introduce biologists and analysts to RNA-seq analysis techniques, we recommend performing all analyses and tutorials in a cloud-computing environment e. This approach has several advantages for both RNA-seq users and instructors. RNA - also contains adenine, guanine and cytosine bases. Machine Learning Tutorials.

Protocol DOI: The identity of a cell or an organism is at least in part defined by its gene expression and therefore analyzing gene expression remains one of the most frequently performed experimental techniques in molecular biology.
Next-generation sequencing technologies are quickly becoming the preferred approach for characterizing and quantifying entire genomes. Even though data produced from these technologies are proving to be the most informative of any thus far, very little attention has been paid to fundamental design aspects of data collection and analysis, namely sampling, randomization, replication, and blocking. We discuss these concepts in an RNA sequencing framework. Using simulations we demonstrate the benefits of collecting replicated RNA sequencing data according to well known statistical designs that partition the sources of biological and technical variation. Examples of these designs and their corresponding models are presented with the goal of testing differential expression.
A basic task in the analysis of count data from RNA-seq is the detection of differentially expressed genes. The count data are presented as a table which reports, for each sample, the number of sequence fragments that have been assigned to each gene. An important analysis question is the quantification and statistical inference of systematic changes between conditions, as compared to within-condition variability. The package DESeq2 provides methods to test for differential expression by use of negative binomial generalized linear models; the estimates of dispersion and logarithmic fold changes incorporate data-driven prior distributions. This vignette explains the use of the package and demonstrates typical workflows. An RNA-seq workflow on the Bioconductor website covers similar material to this vignette but at a slower pace, including the generation of count matrices from FASTQ files.
Metrics details. RNA-sequencing RNA-seq has a wide variety of applications, but no single analysis pipeline can be used in all cases. We review all of the major steps in RNA-seq data analysis, including experimental design, quality control, read alignment, quantification of gene and transcript levels, visualization, differential gene expression, alternative splicing, functional analysis, gene fusion detection and eQTL mapping. We highlight the challenges associated with each step. Finally, we discuss the outlook for novel technologies that are changing the state of the art in transcriptomics.
