Description générale

The spatial folding of genomic DNA plays a crucial role in the regulation of genome activity. However, the biological mechanisms and the physical principles behind that “Stucture/Function” coupling remain largely elusive due to the lack of real quantitave frameworks as well as controlled experiments. The field of “3D genomics” specifically address these questions and is a booming field of research: recent advances in genome-wide mapping and imaging techniques have indeed strikingly improved the resolution at which nuclear genome folding can be analyzed. It has unveiled a multi-scale spatial compartmentalization with increasing evidences that such 3D domains may indeed result from and participate to genome function. In parallel, many computational approaches have been developped to model the spatial organization and dynamics of DNA/chromatin fibers at different scales and in different organisms (prokaryotes/eukaryotes/virus).

Most of these modeling works are based on “home-made code” or open-source distributed code that are optimized for the latest available hardware. Nowadays, the simulation softwares are getting more powerful and sophisticated but also more numerous, based on different languages and architectures. Therefore, in that plethora of tools, it may be puzzling for researchers to identify the appropriate software and hardware, ie that are best customized for the addressed question and the system to model. In that context, the “Groupement de Recherche ADN” over the last eight years brings biologists and physicists working together on the latest hot topics from genome organization. However, the tools that have been developped are not often distributed to the community. In addition, the increase of experimental data resolutions tackle the question of the need of higher complexity models that come along with computational cost.

During this “4D genome computational day”, organized by the CBP, we aim to gather researchers involved in that field. They will first give an overview of their researchs by focusing on the softwares they used/developped. The end of the day will be devoted to a open-table discussion on how to distribute and maintain the codes.
