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.


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

Venue and Time

The course will be hosted in the International Agency for Research on Cancer (IARC-WHO), 150 Cours Albert Thomas 69008 Lyon, France. The participants will get detailed information about a selection of hotels and other arrangements before the course.

The course will start at 9:00 (exception: 10:00 on Monday) and end around 17:00. Precise information will be provided to the participants on due time.


Lyon, France



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



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)

In order to better evaluate if your profile & background match the requirements of this course, would you please take the following survey after application:



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.
