The course is oversubscribed, with a waiting list and is therefore closed.

*This course will take place in Lyon with rules complying to COVID situation (COVID certificate, distances and hygiene). More details in the Additional Information section below. *

IARC (International Agency for Research on Cancer), the doctoral program Staromics of the CUSO (Conférence Universitaire de Suisse Occidentale) and SIB are pleased to co-organize this course. Part of the places will be kept in priority for members of IARC and Staromics.

Overview

Researchers often have access or generate multiple -omics data within a single study. Although each –omics data has been traditionally analysed in isolation, combining possibly complementary data can yield a better understanding of the mechanisms involved in the biological processes. Several integrative approaches are now available to combine such data, which can be regarded as extensions of the standard Principal Component Analysis (PCA).

In this 3.5 day workshop, we will provide an overview of omics data structures, and present different statistical approaches, from simple PCA to more advanced multi-omics dimension reduction methods. For each method, we will cover both its principle and practical aspects. In particular, the course will include dedicated sessions covering the application of the MOFA and mixOmics packages by their respective developers. We plan to have an interactive course with substantial time allocated for discussions.

Audience

This course is addressed to biostatisticians, bioinformaticians and life scientists who analyze omics data from multiple platforms (e.g., metabolomics, proteomics, genomics, transcriptomics) and who want to combine these complementary data to investigate biological mechanisms and identify clusters of individuals

#Learning Objectives At the end of the course, the participants are expected to :

Understand the principles of dimension reduction techniques for single and multi-omics data, including PCA, PLS, MOFA, DIABLO and MINT.
Be able to apply these techniques to their data with R

Prerequisites

Knowledge / competencies

Basic knowledge of some omics data of interest
Basic knowledge or practice of the R software
Basic knowledge of algebra (vectors, matrices) and statistics (random variable, variance, covariance, correlation)

Technical

Own laptop, with R and RStudio softwares installed and, if possible, the mixOmics and MOFA2 packages. Install can be checked & troubleshooted during a pre-workshop online session about 7 days before the start of the workshop.

Agenda

Day -7: Introduction of the attendees & lecturers. Ice-breaker discussion + technical/laptop setup check (~2 hours)

Day 1: Overview of omics data structures and standard dimension reduction techniques.

Day 2: MOFA (Multi-Omics Factor Analysis) - unsupervised multiomics data integration.

Day 3: MixOmics package - supervised multiomics data integration methods.

Day 4 (1/2 day): Downstream analyses and interpretation of the factors
