By modeling genome-wide gene expression and chromatin state data in terms of computationally predicted binding sites, Motif Activity Response Analysis (MARA) allows automatic inference of the key regulators, their targets, and their interactions from high-throughput data in any system. In recent years MARA has been completely automated into an integrated system (ISMARA) webserver that allows any researcher to upload their data and obtain comprehensive predictions of key regulatory network structure in their data. The ISMARA system is quite sophisticated and provides users a large number of interactive possibilities to explore predictions and to generate new analyses of the data and even many experienced users are only aware of a fraction of the possibilities that the system provides. We here propose to provide an in-depth interactive workshop of the ISMARA system.


This workshop should be of interest to any researcher that aims to make computational inferences about gene regulation from gene expression and chromatin state data, including purely experimental researchers. It will be of particular interest to computational biologists and bioinformatic researchers that regulatory analyze gene expression data in their work. No specific bioinformatic skills are prerequisites although a basic understanding of gene expression analysis and transcription factor binding site predictions will be helpful. Attendents are expected to be familiar with the molecular biology of gene regulation in higher eukaryotes.

Learning objectives

The attendants of the tutorial will learn how to use the system, what kind of data ISMARA is able to analyze, and obtain an in-depth exploration of all the analysis results that the system provides including:

  • What are the key regulators, their activities, and the expression profiles of these regulators?
  • What genes and pathways are targeted by each regulator?
  • What is the core network of interactions between key regulators.
  • What are the main regulators of a particular gene and how is this gene's expression affected by each regulator?
  • Exploring embedded links to the String and SwissRegulon databases.
  • How to average across replicate data and how to calculate contrasts between particular samples.
  • How to download comprehensive predictions and potential post-processing of these results.

At the end of the tutorial the attendants should have the expertise to perform sophisticated regulatory network predictions from RNA-seq or ChIP-seq data using the ISMARA system.​


Knowledge / competencies

Knowledge of the molecular biology of gene regulation in higher eukaryotes.


Participants should bring their own laptops and, whenever possible, own data. Wireless connection will be needed for users to be able to interact with the system.
