Overview
Description
This workshop demonstrates the use of the GeneTonic package to integrate and explore the results of RNA-seq experiments, in the context of differential expression and functional enrichment analyses.
This will be proposed as a lab session that combines an instructor-led live demo, followed by hands-on experimentation guided by exercises, hints, and solutions that participants may continue to use after the workshop.
The instructor-led live demo comprises three parts:
- Overview of the RNA-seq differential expression workflow.
- Introduction to the GeneTonic package and its functionality.
- Hands-on exercises and discussion.
Participants are encouraged to ask questions at any time during the workshop.
Pre-requisites
- Basic knowledge of RNA-seq analysis workflow
- Familiarity with concepts proper of differential expression analysis (e.g. in the DESeq2 framework, https://bioconductor.org/packages/DESeq2)
- Familiarity with functional enrichment analysis concepts (e.g. with the clusterProfiler package, or using the topGO wrapper included in the pcaExplorer package)
We recommend to use the latest version of R (>= 4.0.0) and the latest release of Bioconductor version (3.13).
Install the GeneTonic package
BiocManager::install("GeneTonic")
# alternatively, the development version directly from GitHub
BiocManager::install("federicomarini/GeneTonic")Participation
Attendees will participate by following along a presentation introducing the GeneTonic package, RMarkdown documents which describe the tasks to perform, trying variations of provided code, and asking questions throughout the workshop.
Learning goals
- Integrate the different components from the Differential Expression analysis workflow
- Utilize interactive web applications to efficiently extract information of the combined input objects
- Adopt means to generate reproducible reports to capture the results of the live exploration
Learning objectives
- Setup a local environment to run GeneTonic on the results of own RNA-seq experiments
- Interact with the core components of GeneTonic to inspect the provided datasets
- Create a variety of interactive visualizations to summarize and help interpret the data at hand
- Practice the combination of interactivity and reproducibility to combine the advantages of these aspects in a single computational workflow
