Using the Trinity Framework for De novo Transcriptome Assembly, Annotation, and Downstream Expression Studies

June 12-16, 2017, Berlin (Germany) http://www.physalia-courses.org/courses/course11/

Instructors: Brian Haas (Senior Computational Biologist at the Broad Institute at MIT and Harvard University)

Course Overview:

RNA-Seq technology has been transformative in our ability to explore gene content and gene expression in all realms of biology, and de novo transcriptome assembly has enabled opportunities to expand transcriptome analysis to non-model organisms. This workshop provides an overview of modern applications of transcriptome sequencing and popular tools and algorithms for exploring transcript reconstruction and expression analysis in a genome-free manner, leveraging the Trinity software and analysis framework. Attendees will perform quality assessment of Illumina RNA-Seq data, assemble a transcriptome using Trinity, quantify transcript expression, leverage Bioconductor tools for differential expression analysis, and apply Trinotate to functionally annotate transcripts. Additional methods will be explored for characterizing the assembled transcriptome and revealing biological findings.

Intended Audience:

This workshop is aimed primarily at biologist researchers that have basic bioinformatics skills and are pursuing RNA-Seq projects in non-model organisms. Attendees will gain skills needed to successfully approach transcriptome sequencing, de novo transcriptome assembly, expression analysis, and functional annotation as applied to organisms lacking a high quality reference genome sequence.

Teaching format:

The workshop will be delivered over the course of four and a half days, with each session entailing lectures followed by practical hands-on sessions. Most all computing will be done on the cloud and attendees will use their own laptop computers with the Google Chrome web browser providing all the necessary interfaces to the cloud computing environment, including the linux command terminal.

Assumed background for the participants:

Basic experience with linux command-line execution and execution of bioinformatics tools would be helpful. We will begin the course with a review of basic linux commands and operations as a refresher. No programming or scripting knowledge is required.

Curriculum:

Day 1: Intro to the Trinity RNA-Seq workshop • Intro to RNA-Seq • Intro to next-gen sequence analysis • Overview of unix and workshop setup o Practical: exploring the computational infrastructure • Read quality assessment and trimming o Practical: using FASTQC and TRIMMOMATIC

Day 2: Trinity de novo assembly, expression quantitation, and assembly QC • Overview of Trinity de novo transcriptome assembly o Practical: assemble rna-seq data using Trinity • Intro to expression quantification using RNA-Seq o Practical: quantify expression for Trinity assembly • Initial data exploration: assembly quality, and QC samples and replicates o Practical: using IGV o Practical: replicate correlation matrix and PCA

Day 3: Differential expression analysis • Overview of statistical methods for differential expression (DE). o Practical: using Bioconductor tools for DE analysis. • Transcript clustering and expression profiling o Practical: generating heatmaps and extracting transcript clusters.

Day 4: Functional annotation and Functional enrichment studies • Overview of methods for functional annotation o Practical: applying Trinotate to find coding regions in transcripts and predict biological function. • Overview of functional enrichment analysis o Practical: applying GOseq to identify significantly enriched Gene Ontology categories among transcript clusters.

Day 5: Review and custom data analyses
