Overview
DNA sequence analysis generates large volumes of data that present challenging bioinformatic and statistical problems. This tutorial introduces established and new Bioconductor packages and workflows for analyzing sequence data. The
Bioconductor project is a widely used collection of nearly 1000 R packages for high-throughput genomic analysis. Approaches for efficiently manipulating sequences and alignments and other common work flows will be covered along with the unique statistical challenges associated with 'RNAseq', variant annotation and other experiments. The emphasis is on exploratory analysis, and the analysis of designed experiments. The workshop will touch on the Biostrings, ShortRead, GenomicRanges, DESeq2, VariantAnnotation, and other packages, with short exercises to illustrate the functionality of each package.
Goals
1. Gain overall familiarity with Bioconductor packages for high-throughput sequence analysis, including Bioconductor vignettes and classes.
2. Obtain experience running bioinformatic workflows for data quality assessment, RNA-seq differential expression, and manipulating variant call format files.
3. Appreciate the importance of ranges and range-based manipulation for modern genomic analysis.
4. Learn 'best practices' for working with large data.
Outline
- Introduction to Bioconductor － packages and classes
- Short work flows
- Exploring sequences and alignments
- RNA-seq: a high-level tour
- Annotating variants
Prerequisites
The workshop assumes an intermediate level of familiarity with R, and basic understanding of biological and technological aspects of high-throughput sequence analysis. Participants should come prepared with a modern wireless-enabled laptop and web browser installed.
Intended Audience
This workshop is for professional bioinformaticians and statisticians intending to use R/Bioconductor for analysis and comprehension of high-throughput sequence data.
