Immersive Molecular Modelling Workshop

Immersive Molecular Modelling
(ImmMolMod)
Workshop

Friday, October 19, 2018, 1 – 3:30* pm, University of Konstanz, PZ1001

* As we will have basic hands-on demos included, it might take a bit longer than 3:30 pm.

In contrast to many other biochemical research areas where the applicability of immersive visualization and analysis still has to be proven, molecular data profits from spatial visualization since many years. In this workshop, a number of tools will be presented which fall into the area of molecular modelling, docking and simulation, making use of Virtual and Augmented Reality-related technologies.

Preliminary Program

  • 1:00 – 1:15 pm Welcome
  • 1:15 – 1:45 pm Marc Baaden
    • Immersive visual exploration of biomolecular systems in virtual reality
      • Abstract: For several years now, my team pursues the goal to study complex molecular assemblies through interactive visualization, manipulation and analysis approaches to aid hypothesis generation and exploration of complex datasets. The UnityMol framework [1] forms a central tool for these investigations and is based on the Unity3D game engine. A first line of research tries to help with the 3D context, for instance through content-guided navigation, exploded views and semantic links between molecular objects and their analysis data [2].
        Concerning the molecular representations, we extended the UnityMol repertoire to include specific visualizations for sugar molecules [3] and have now also included coarse-grained systems by default. These are particularly apt for interactive simulations, even in the classroom or via crowdsourcing. A particular focus lies on the integration of dedicated hardware such as large, high-resolution display walls, or more recently head-mounted virtual reality headsets or augmented reality setups.
        The latest version of our UnityMol VR implementation will be demoed.

      • CV: Marc Baaden studies membrane proteins using extensive large-scale simulations, such as for the bacterial GLIC ion channel (gating, anesthesia, …), a homolog of the nicotinic receptor. This is completed by innovative work at the interface between biology, chemistry and computer sciences (virtual reality and scientific visualization).

    • Coffee Break
  • 2:30 – 3:00 pm Michael Krone
    • Immersive Analytics for Molecular Dynamics Simulations
      • Abstract: Interactive visualization is commonly used as a tool for the analysis of molecular structures, especially for molecular simulations. Many different molecular models have been developed to show individual properties of the simulated molecules, resulting in complex three-dimensional depictions. Immersive technology such as stereoscopic rendering has been adopted for molecular visualization early on, as it makes it easier to understand the spatial relations between these complex structures. In my talk, I will show how we have applied immersive technologies to facilitate the visual analysis of biomolecular simulation data in the last 10 years, ranging from classical stereoscopic high-resolution tiled displays (so-called Powerwalls) to modern head-mounted displays that enable the use of Augmented Reality. Besides stereoscopic rendering, I will also briefly discuss the use of spatial audio as an additional immersive technology, which is to date rarely used in molecular visualization.
      • CV: Michael Krone is a junior professor (assistant professor) at the Eberhard Karls University of Tübingen in Germany, where he leads the Big Data Visual Analytics research group. He is also principle investigator in a Czech-German research project funded by the German Research Foundation. He received a diploma in Computer Science (equivalent to M.Sc. in CS) in 2008 and his Ph.D. in 2015 from the University of Stuttgart. In 2016 and 2017, he had appointments as guest lecturer for Computer Graphics at the Ludwig Maximilian University of Munich. His main research interests are in scientific visualization and visual analytics for life sciences, especially the interactive visual analysis of molecular structures, and GPU-accelerated computing.

  • 3:00 – 3:30 pm Björn Sommer
    • Membrane Modeling with MembraneEditor
      • Abstract: The modeling of homogeneous membranes with a single lipid type is a quite simple task which can be done by writing a simple script compatible to tools like VMD. But if the membrane should contain multiple lipid types, different proteins, maybe lipid rafts and be of different shapes (like circular ones or vesicular), things are getting complicated. Then, the CELLmicrocosmos 2.2 MembraneEditor is a tool which has been already used for many publications to set up heterogeneous membranes or vesicles [1]. Moreover, the MembraneEditor supports stereoscopic visualization during the modeling process. The so-generated membranes can be used for molecular dynamic simulations with, e.g., Gromacs, and then analyzed with tools like APL@Voro [2],
        Here, we will give a short live intro to MembraneEditor. You may bring you laptop and preinstall Java and the MembraneEditor available from:
